I grew up using Windows, and right around the time OS X was released, I switched over. I gotta say, I've never looked back. Sure, it can't run some programs Windows can, but it repays that sevenfold with what can be used.
Unfortunately, however, I'm stuck on 10.4 for the time being because the dipspits at the 'genius' desk managed to screw up. Again. >>
'Oh well 10.5 isn't the native system on your G4, so we can't put it on there.' Well, has it ever occurred to you that someone might choose to use a PPC? It just so happens that I'm against the recent move to Intel, and G4 is the last laptop made. Suuure, if y'all cared enough to make a G5 PowerBook, I would freakin' have one! But noo, we have to move closer and closer to universal anonymity until there's no computers left but a thin screen that plays thoughtless action movies and dispenses high fructose lazy organic syrup juice!
Gah!
