OSX
I would say Im a pretty ardent member of the Apple coommunity. I have a TiBook and a G4 tower. The tower still runs OS9 (been too lazy to switch it over--it needs a cleaning/overhaul first) but the Laptop runs OSX like a beauty. I use Cinema4D for my 3D animation major, and OSX is fun, clean, stable, and durable. I dont know **** about unix programming, nor do I care. All I know is that OSX WORKS. I have to admit though, its no fun if you dont have applications to use it with! But now that Photoshop is out, I would guess that people will move more quickly to X.
I was afraid at first, but now that Ive switched--Im telling you---OS9 looks clunky, dated, and boring.
