I own a 1.2 GHz, 12" iBook dating from 2004. I bought it as a refurb a year ago and so far it's been fine. I also own a PPC Mini which has been a great (and cheap!) little desktop unit for me. I was planning on buying the new upgraded Mini for faster (yet still cheap!) performance at home, because I could still use the iBook as my mobile unit. (My computing needs are modest, but I do get some slowdowns from time to time, and anyway it's probably time to get on the Intel bandwagon.) I decided against a Macbook doing double duty because I didn't want to be always docking and un-docking it from my office peripherals, and because I feel more secure with 2 computers in case one has to go in for repairs. But recently I've been reading on the Low End Mac site about a design defect in the G4 iBook that causes spontaneous shutdowns, etc, and it sounds like this model may have a short-ish lifespan. Not as bad as the logic board problem on the G3 iBooks, but still...it makes me stop and reflect on whether my buying plans are sensible. So now I'm confused again. In an ideal world, I'd buy the new Mini AND the Macbook, but in that world I have a better-paying job.
