It's nothing to do with the apps (if they are up-to-date), more to do with investment in newer technologies (those apps not being up-to-date), for example, I am sent a load of MPG-2 files which Quicktime won't touch. These were created with some out of date application that was installed with XP on their PC's a few years back. The only thing that will play them is the VLC player. Great. I can playback, but I can't edit, or update, without myself having to spend even more money (which I haven't got).
It's lazy British IT basically, "if it works, don't fix it" type attitude, which is fine, if that whole department doesn't update, but your scr*wed if anything leaves the room. Generally it seems that applications don't get updated unless the operating system gets a boost.
Another interesting example was a department I was working in recently where CS5 kept crashing badly on XP. But after a whole load of internet searching, it was found that updating to Windows 7 was curing most peoples problems. The department updated only one PC to W7, and the problem went away. 
Okay, they probably just need to update their apps, but many IT departments' budgets don't appear to stretch this far- at least in England. I think IT departments in the USA are far better at this and more 'on the ball' than we are!
