Given everything Steve just said, specifically everything that comes in "the next version" = 10.2 -- Waite until they package 10.2 WITH the system, of course only if your actually buying one from Apple. They are not doing the same thing they did w/ 10.1 i.e. give the update away for free. This will be a paid for update. They should be packaging 10.2 with there new systems soon so you shouldn't have to waite too long. I use 10.1.5 on my Powerbook G3 (Pismo - 400MHz G3 w/ 320MB RAM) and it ROCKS!! You will also definetely need to get FINK installed and running. It's great. Uses the apt-get debian package menagement system and uses it's own directory structure (won't mess w/ OS X at all). There are also GNU curses/ncurses lib's around that I've seen ported. Don't know the versions of those but if those outdated packages are a real problem that might be the way to go. Also, Oroborus has a Mac OS X like scheme. That is the window manager that XonX sends with XDarwin. It's supposed to look just like OS X so your desktop looks the same when you jump into Xwindows (just in case you fella's want the look of a Mac but don't wanna move to the PPC). :-) Just some things I've found on my Mac OS X journy... HTH, sim
