Still not null match, pilou. Because both sculptris (btw, i use sculptris) and zbrush work wonderful. But in case of SU, both free and pro suffer from the same weaknesses: they are underdeveloped and the pro is still overpriced for what it offers.
The point of this topic was to draw attention to how others sell their software: they meet price with quality.
I expect by the time when SketchUp will reach the robustness of any other major software to cost like AutoCad. And by robustness i don't mean to be complicated, but to really do properly what is supposed to do already.
-proper uv-mapping
-fix scenes renaming bug
-faster and more responsive LayOut
-text mismatch fixed between SU and LO
-text mismatch fixed in LO between edit mode and rendered mode
-less bugsplats
-some really important features introduced by default instead of being needed contributed plugins (like Layrrs Panel)
...and many others.
Can you imagine SketchUp's price then? Like $$$$... and this was my point: zbrush can do much better and syill keeping price low. One more thing: zbrush users are a very narrow niche, another reason to increase price. SU can be used by artists, hobbysts, architects, engineergs, teachers, psychologists... etc.
And your comparison would have been closer to reality if you had chosen Edison, not Tesla ... because Edison was a prick that used Tesla to make money and didn't repaid accordingly )) ...kind of what Trimble does with SketchUp.
