Of course its here to stay, theres no arguing that. Whta im trying to work out/discuss is wether UIs and software will ever reach the point where they are a viable alternative. (thats actualyl pretty different from what i wrote in the OP, but it raises pretty similar issues.)
hmm,
laptop computer: £1000
mouse: £10
skecthup pro: $495drawing on the back of an old letter using a pencil you found on a colleagues desk: priceless.
there are some techniques in design you can buy, for everything else there's sketching.

CHris, none the less it is the designers fault more than anything else, he chose the wrong method of presentation for the client, that doesnt mean that there is something at fault with the technology. In the same way as if you tried to present a quick sketch for the final realisation of a project.
Pav, do you have a computer? id say its a fairly standard peice of equipment these days. Not so much with swanky interfaces (tablets, tablet PCs etc.) but give it 10 years or so, im sure there will be some new interface device we could have never lived without.

i agree with you on computers being a standard piece of equipment, but like you say the "swanky interfaces" not so much (at this current moment in time). let's not forget though that these swanky interfaces, pretty much still rely on sketching techniques, graphics tablets, tablet PCs, are still fundamentally based on the good old pen and paper.
who knows, maybe there will be some kind of "computer paper" (there probably already is) but this is still essentially a development on sketching.
prehistoric man had cave walls and natural pigments, the egyptians had papyrus and ink, modern man a sketchbook and a pencil.
i'm not saying that we wont be drawing on tablet pc's in the furure, i'm almost certain we will be, but the question was about whether we would be designing in CAD, and as far as i am concerned this is just an evolution in sketching, not a change in the way ideas are put down.pav

In the architecture firm I work at we always do sketches first. We've NEVER started a design on CAD! It seems absolutely pointless to try to design anything on CAD when it takes much longer to do then when using pen and paper. Once we get the go ahead on the design from the sketches... we then start to build models and technical documents! Sketchup can be fast but it is still not as fast as pen and paper!

DO you think its ever going to reach the point where it is possible ot do ideas in CAD?
Pav, more pondering to do...

OPEN LIST
feel free to edit and complete itPencil pros:
- doesn't need power supply
- no batteries
- cheap to buy
- few maintenance
- the weight is ludicrous and you can carry it everywhere without backpack or case
- no boot or startup time required, no reboot!!
- no software updates, no patches, no malware
- no snobbish win vs mac vs linux: it really just works
Pencil cons:
- doesn't work well in the darkness
- you can not copy and paste
- if you want to email a sketch, first you have to scan or take a picture of it
- no undo! (well, I remember the age when I had to erase ink lines with a blade)
- color fills and patterns are not so quick and easy to generate.
- ink color choice reduced if compared with a computer screen. Drawing in truecolor by hand kills the rendering time of your organic hardware.
- most of carbon units cannot easily generate shadows neither produce a decent perspective or even figure out how it works: the best trained units take a lot of time to operate such functions
Tablet pros and cons: just reverse the above list.
Future evolutions, not so far to come: oled diplays look very promising.
Take a look to MS Surface:

Precisely the point. Well done!

Well my workflow [in landscape design] hasn't included anything other than a keyboard for eight or nine years...I just never do preliminary sketches.
I find I can get concepts on screen as fast as I need to... with editing/drawing tools like delete, copy, mirror etc far quicker and more accurate than any pencil.I start in ACAD....quickly migrate to SU....where most of the creative work is done, and then export back to ACAD for the working drawings.
Something like a 9.1 EeePC would make all this truely portable and independant of the desk [top].

ideas come from people. Getting those ideas out of your head and in front of other people is simply a user preference based on your capabilities with the medium.
Having said that I think we all employ some measure of hand drawing to visualize our thoughts but I have found that the quicker I get my thoughts into the computer the more flexibility I have to massage those thoughts and present them. What I love about computers is they are output "independent" IE: I can print out at 1/8" scale 1/4" scale 1/2" scale etc. I can print to my 11x17 laser printer, my epson 4000 color printer, or my large format plotter. So I can create something once and use it multiple times.
I agree that at times I just need to take a print and sketch ideas onto it. but within seconds of having an idea resolve on paper I jump back into the computer.
There is no going back now. I doubt seriously that students coming out of schools today have the manual drafting skills necessary to complete all the required drawings to convey an idea by hand. SO in that regard at some point all of us who were taught manual drafting and perspective drawing, and water color, etc. in school, at some point we are no longer in charge and the students who don't have or value those skills or for that matter need them will take over and just like any craft if the younger generation does not perpetuate it it will fade away.

Well said Phil. I think it all depends on what you are comfortable with and task at hand. Although I am biased to hand drawing in some cases there is no way I could create some designs on paper vs computer especially when a lot of repetitive geomerty is involed. Think about the parametric high rise designs that are created these days. I'm sure by now there are some guy's out there that have quickly done some masterful works on the computer w/o touching pencil n paper.
Ive seen some sculptors create some master pcs w/o ever touching a drawing. It
has more to do with the individuals skill and comfort level and choosing the right tool for the job. -
Sorry for my poor english, but I don't know another word for it: vitality
This is the real difference between pencil and computer aided drawings.
When i draw with a pencil, body and mind (brain, spirit) are one single thing, work together. There's no bezier curve that can emulate a hand drawn line. Computer drawing is more an intellectual act, an act of the mind olny. Maybe with the exception of tablet input devices, there's not any real good interface between human and calculator. Computers can fasten your work, but can't bring alive your work.Otherwise, how do you explain the plethora of attempts to make your computer drawings more "natural", from the edge styles of sketchup to the watercolor tutorials for photoshop masters: just look at the "how to make it watercolor like" threads that there are only in this forum.
No it's not the some as real watercolor. The fragrance of the paper, the graininess/texture of the paper, the imperfections that make it unique, the real colors: a printer gamut is usually very limited: you can never obtain deep blues, decent purples, blilliant greens. Even the rgb gamut of the best screens is something limited.
The some applies to all "natural" mediums, not only watercolor.You can draw some masterpieces with your computer, but up to me they lack in vitality. It's many years that I try to achieve a vital result with computer, but it looks like the holy graal quest.
I wish I had more time to draw without computer.
snobbishly yours

Mateo is on to something that I feel should be mentioned also.
"Pleasure"
Doing drawings by hand is pleasurable, enjoyable, there is an ephemeral feedback between the media and the user. The feeling of the pencil as it bumps along on the paper, the feedback you get that the tip of the lead is getting dull and the brains response to roll your fingers. the unexpected results when the paper absorbs the watercolor pigment and the visual end result is pleasing to your eyes even though you had not intended it that way. There is a symbiotic inter connectedness between the creator and the medium. The computer has something similar but there is a lag time and the medium never changes and is not random.
there are logical reasons why the computer is the correct choice to express ideas in a busy and demanding world, however the allure and pure pleasure of creating something with ones own hand will never be replace by the computer.
I find myself in situations at meetings where my sketching skills have diminished because of lack of use and I don't have the ability to completely illustrate an idea to clients. My brain says if only I had my laptop fired up and could model it in sketchup I could be more clear.
Sketchup is the first application that I actually consider an "on the spot" medium. it's simple user interface and powerful capabilities seperate it form its bloated competition.
I would never consider having AutoCAD running in a live presentation because its so lifeless and lacks any character.

I believe (and I hope I am right, because it is my greatest dream), that the future of architects and designers will be to use a pen on a computer screen.
in my opinion the fusion of handdrawing and computer aided design is the only sensible solution.
the simple reason for that - try to write your name with a mouse... you will barely succeed in producing clean hand writing. you are simply much more precise with a pen than with a mouse.of course technology has to improve before that truely works. but it is not too far in the future anymore (I hope
)even today there exist prototypes of so called e-paper that are as thin as a fraction of a millimeter and are equal to newspapers in terms of contrast (because they really behave like ink on paper, reflecting light instead of emmiting it).
at the moment these displays are restricted in size to some inches. but the near future they will be available in A3 size with a resolution high enough to give a true, pixelfree image, even when looking at it upclose.I imagine using your hands (similar to the iPhone) to navigate across your canvas. you can choose to stick the drawing stage to your screen to imitate the behavour of real paper. but if you run out of space you can simply unlock it and move it arround.
the touchscreen will destinguish between hand- and pen-input. that enables you for example to rest your and on the screen when drawing with the pen. drumming with 4 fingers of one hand on the screen in a short succession calles up a context menue. otherwise the screen stays completely free of any buttons (except of a colour pallete perhaps).the tip of the pen will be a high-tech device on it's own, not only measuring the precise pressure and angle of the pen, but also changing it's smoothness (through a material that changes it's attributes when recieving an electric current). thus the pen can simulate different types of pens (like pencil, marker, brush) and give the impression of drawing on rough canvas (instead of completely clean plastic).
you start your design with an interface, that is close to Photoshop. you sketch like with a real pencil. but you have the advantages of a computer - you can change your pen without laying your drawing device out of your hand, you can change colours by tipping it on a button on the screen. most important you have a "undo" function. you can draw in layers easily, fill faces with colour, draw only in a selection - everything a piece of software can provide.
in addition to that you may have aids to slightly correct your lines to a coordinate system when active or to help you drawing a precise circle, ellipse, rectangle...when you finished your first sketch, you can use the SketchUp tools, push/pull in the first place, to advance into 3D - within the same application. this new SketchUp will refer to faces rather than to edges (because you draw lots of small lines, when sketching). you can define the grade of simplification (like ignoring small lines, closing gaps) and angle-/shape-correction (putting lines to a right angle, where obviously intended, translating sketched curves to arcs, circles, bezier-curves), even choose different correction values for different parts of the same drawing.
if you need a break, you will just leave your sketching tablet lying on the table. the drawing will still be visible, because an e-paper display doesn't need engergy to display information (only for changing it).
you can easily transfer sketches/models from your tablet to the large table-display, simply by performing a dragging movement starting on the tablet display (lying on the table) and ending on the table-display. because it is one continuous motion (same speed, finger tip size and curve) the two systems will automatically synchronize the data.
then I poste one drawing by simply dragging it into one of the SCF gallery threads. one of you guys sketches some suggestions on a new layer and posts it back in the thread (only the layer with coordinate information, which I then drag onto my drawing...)
sorry guys, got carried away way too far
could go on for hours.essence of what I wanted to say: the natural and intuitiv use of a pen will be combined with the precision and multifunctionality of a computer - in sketching, as well as in construction drawing.

Ahh but Phil, you said:
Doing drawings by hand is pleasurable, enjoyable, there is an ephemeral feedback between the media and the user.
This is only true when one has acquired an ability to draw/sketch/paint by hand. For some of us the learning curve is considerably steeper than it is for others. It has taken me 29 years to get to a point where every once in a while I feel "pleasure" while drawing by hand. Whereas I had that feelin early in my pre-teens doing ansi art for BBS's in the days before AOL had tapped in to this new thing called the internet. My ansi art was very popular and I got quite good at because I had an eye for color and composition, but it didn't require that I needed to be able to hold my hand still and draw a straight a line (which I still can't do!). So my point is, hand drawing doesn't give everyone pleasure - for some, its quite painful really.
That being said, the better I've gotten in 3d and photoshop, the more I've been wanting to develop some true hand drawing skills and that is why I work on it quite regularly now. I am finally getting better, and now that I'm getting better, it is finally becoming faster than 3d modeling for rough conceptualization to a certain extent. And some nights after I've put the little girls in bed, when the stars are aligned just, I sit down and watercolor and I am pleased with the results
Chris
PS: My current avatar is a plein air watercolor I'm proud of! I've even started my own little art blog just to chronicle my successes and failures (the links in my signature below). I try to post a lot of my stuff, good and bad, so hopefully in a few years time I'll be able to see the progress I've made in my hand-art skillz
Anyhow interesting conversation and I think it all boils down to what one enjoys, but its not necessarily true that everyone finds joy in hand drawing - yet! -
Here you go Paris, the Cintiq. Its the same idea as a tablet PC, but it is made by Wacom, who make drawing tablets. So its really geared for drawing and art. And if anyone doesn't have something for me for my birthday (in December) yet.....hint hint. PM me and I'll give you my shipping address

I think this idea http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=11205 will free us from a lot of restricting hardware.
Imagin two hand modeling and sculpting,wherby the whii reconises your hands and there movements.Greetings Bep van Malde
