I think a lot of people missed the point of my original post however... which is, if you get the chance to try it, do... for us that are running it, well... you know.

OS/X is nix to the core. It runs commercial apps that Linux can't touch (if you want them - they are there -that's all I'm saying :-P)... There is a bevy of ported freeware from BSD (TeXShop is a beautiful example) land. It has installation routines that pass the "mom" test (unlike tar -xvf, etc...). The graphics are outstanding (display postscript gives a sharp image - good for older farts like me), it has been stable as hell, it runs extremely well on my G4 400Mhz (not exactly a raw processing speed demon) and available out outlets for <$1000. So just what am I saying?

Meet the new boss, same as the old boss... (only from Apple)...
