I love my Win98 PC
But it seems you don't know too much about it. Windows can be EMULATED on a Mac. It seems to be really stable. So you can also play win games and apps on a mac.
Macs are also a bit faster than regular new windows PCs. But what do you expect for a pc that's 3x more expensive than a regular PC? And "Macs are easy to use", I think my PC is already too easy to use, I can do about everything I want with it!
But those PowerPCs are really faster than Intel-PCs. A while ago I saw a test on TV. They compared the (new) PIII-600 with the PowerPC. And they used images from mars. The Pentium reached about 2 FPS, while the PowerPC showed them really smooth like a movie, about 30 FPS.
conclusion: unless your an idiot, stick to the WIntel PC!
