I'm a recent "switcher" from the PC world to Mac. I ordered a new G5, but have yet to receive it. I was at the Apple store in Towson, MD messing with the 1.8 G5 they have on display. I was screwing around with iDVD when the system completly crashed. Complete freeze, no mouse movement, keyboard response, etc. The store clerk had to reset the box with the power button. Anyway, this was a bit shocking to me. I'm switching to Mac in the hopes of improved stability, ease of use, etc. I guess my concerns are... Do crashes like this occur often? Is this the old Rev A crap? Is this just some isolated incident due to an abused demo model? Any ideas from the mac-experts out there?
