I've been a mac user for years and overall, have never really had any complaints, but.....
recently the printing company I do graphics for upgraded me to a brand new G4 and I'm not that impressed. Yes it is FASTER, but it's also loud as fuck (very loud high pitched whine), the cd/dvd drive is very picky with enhanced cd's (I put in PT in absentia today and it fucking errored), also I've already gotten the "BOMB" on startup several times with some lame ass address error bullshit. This is a $3500 machine.
Still....I'll put up with that shit over having to use a windoze machine. (personal preference) I'm not trying to start a mac/pc war, although that might be fun.
