I hope that some of the people here are using Maya 8.5, maybe even PLE version. I've just downloaded Maya 8.5, and I was wondering what are the huge differences between 8.5 PLE and 6.5 Unlimited? Are the numbers that important? Are huge changes made every update?

Please shed some light on what is new here, should I stay with Unlimited 6.5, or use 8.5 with the annoying no commercial use renders?

Thanks,
Chris
