Well, I'm a PC user, a Linux (Ubuntu, KDE enviro's for people with far too much spare time), and soon to be a mac user too!
They all work. As far as PC crashing issues now-a-days, with w7, there's virtually no room to bitch about it crashing. If a 1GHz (1GB ddr3) Intel Atom can handle w7, the aero theme and quite a lot of apps open too, i can't see the faults.
But mac's are beautiful, and i'm vain.
