i crash the imac at work about once a week and thats just opening and replying to emails and righting up memos (thank god for the spell checker). my pc at home is where i sent this from and also were i work on the music doesnt really ever crash unless im really abusing it. the i mac kind of crashes out of nowhere. i dont use the pc alot for audio recording i guess the platform that supports the softwear and outboard hardware that you like is the one thats best. i'll never get a mac but thats just me
