The new(er,est?) Mac iBook2's are rather nice and cheap (and quiet --
faster and quieter than my wife's slightly older Sony R505, for
example, and comparably sized).
Plus, if you have the know-how, it makes the perfect Linux laptop :-)
(screams from OS-X and Mac die-hards in the background...), except for
a lack of ability to handle external displays and presentations (but
you really do want Mac OS X and the joys of Mac user friendly
auto-detect/config to make that part completely painless).
You still can run OS9 and OSX from within Linux, if you really want to
(MacOnLinux works, though I'm having problems with getting OS9 on > 8
bit graphics, but who needs it?).
Now, if you are looking for a desktop replacement rather than a small
notebook ("small" was the operative word for me, 12" screen the max I
would tolerate), you probably want an AMD or Intel-based laptop. The
TiBook is nice and classy, but probably not as cost effective.
best,
