wifi4lyfe,
FWIW, if I were you I would try to save up a little more $$ and maybe go for one of the refurb 800Mhz G4 iBooks from Apple. The refurbs come with a full warranty and earlier this evening they listed a nicely configured G4 12" iBook for around $849. The video and CPU are definitely better on the newer machines and you will have a better chance of being able to play some games.
The iBooks are quite nice, I'm about to buy one for my daughter for high school, I fully expect it to last for 4 years. Nice and rugged, good battery life and WiFi reception.
If you plan on having the machine for awhile definitely worth it to get the very best config that you can.
Oh, and to find the Apple refurbs go to the
Apple Online, hit the Store tab and look down the left-hand side to the red "specials" tag. If you see something you like don't wait, they go quickly. Also if you have an Apple Store nearby they often have refurbs or demos for good prices.
Good luck,
fraz
