here is an obvious change that was put on the little info card with 10 this year, the software is changing to DVD format instead of the normal CD format. I think the program will get a lot bigger and take up more space. Which is bad news if it happens as i run off a PIII and have only like 40 gigs of memory. My comp is SLOW when i run Inventor 10, so the new one, whether 11 or 12, will make it so i can only use Inventor or the rest of my computer at one time.
