it comes down to this: the mac is not for you're primary measurement of a computer's performance is that of playing games. so for you gamers out there, you win, the mac does not 0wn3r in this arena, and mac users are not oblivious to this. apple has never billed itself as the ultimate gaming system, so you would be wasting oxygen to fault it for not being something they never claimed it to be.
the mac, even with the G5, is still not as fast as the top of the intel line. so what.
show me an intel box for $3k that is 64 bit. show me an intel box that will gladly accept 8gb of memory without voiding the warranty. show me an intel box in that pricepoint which runs a unix-based OS that your grandmother can not only install and easily use, but can edit movies with no prior experience.
what the majority of us fail to realize is that apple computer offers the best turnkey computing solution out there for 95% of the computer using public.
you are probably asking, "why is this psycho mac fanatic posting in sagerforums?" perhaps....and a valid question that would be. i personally enjoy my 8887/XP pro for the most part...hell i even got a random coffee shop marriage proposal from some pubescant teenie bopper because of the black beauty that is the 8887. i am first and foremost a mac user, but unfortunately, Autocad is no longer made for the mac, so as a mac user i got the best non-mac laptop system on the planet....
