Thank you all for the answers, though it still makes my choice difficult
Actually boottime, Marcus, don't mean anything to me and would certainly not be a reason to go to a Mac. Once my pc is started it stays on untill I go to sleep so hopefully we will not be comparing shutdown speeds now
In June I will be going to some kind of Final cut studio 2 workshop in Brussels were Mac people are presenting their updated editing suite so I have a better idea what the possibilities are. Especially if it's worth the big investment and steep learing curve (Considering I would be switching from OS and NLE.)
