Im REALLy really thinking about just getting maya complete, but, under system requirements it only says xp professional, not home, and that might have to do with all of maya, which would create a setback for me because I got "home" for christmas.
home for christmas 
any suggestions? Also, if I am thinking of just getting maya complete, I was thinking and looking at cinema 4d lately, and I really like it. What would the positives and negatives between the two be?
