Hi All:- Having brainwashed my mother into the cult of Mac, she'd like to upgrade from the clamshell iBook I picked up for her a couple of years ago. She doesn't want to upgrade in a hurry, but, being retired, and not being a power-user she doesn't want to spend too much money, either. So I've located two options for her:- - a 600mhz iBook G3 ($490) - a 1ghz iBook G4 ($792) She seems to be leaning toward the G3, but I'm wary, as my own (much used) G3 iBook died after 4 years (of heavy use). Or will the g3 last her? She will not be doing much more than browsing, mailing and word processing... I know that the G3 will do this just fine under 10.3 - but will the machine last as long, do you think? Opinions welcome! Thanks.
