I think it's bullsh*t that my friend has a copy of Maya Unlimited, and I can't even buy that for OS X, like I went to a Maya Seminar in NYC one day (gotta miss school for it 😀 ) All it was was like this "buy this yadda yadda..." But as soon as the guy mentioned that it was not the 'Unlimited' version, i.e., no fabric or fur renderers, etc. A whole bunch of people just kinda asked some questions, got up, and left. That was heartbreaking, it's like the guy was showing us some REALLY cool stuff, but as soon as he's like "...they may add it later if the userbase becomes large enough...", it turned alot of people off, how are you going to get a large user base if you're not giving people the whole product? In my opinion, that sounds like a plan that was designed to fail...maybe not for you or me, but no serious design studio would bother if it wasn't a full featured product.
