most of the Steve Jackson games are pretty fun, if silly. I have fond memories of The Awful Green Things from Outer Space and OGRE, but those might be hard to find.
@ben: I've played Carcassonne on the Xbox (of all places) and it's pretty interesting. I can see how the end-game scoring piece could be a bit complicated without a computer, but kind of fun just the same. For me, I'm not sure it has the same social aspect as Settlers — the trading keeps everything interesting, but nonetheless sounds like it's worth checking out.
to echo mrz' and ms. onymous' comments, the later Logitech cameras (with the Vista labelling) work with most versions of OS X. I guess there were some issues with 10.4.9 (or is it .10?), but they should do the trick. Check out MacInTouch for details.
I wish Apple'd issue a newer version of the Firewire iSight. They're great cameras.
