I am waiting for my imac 20 to arrive, so I am thinking of getting an inexpensive notebook as a backup for viewing photos and surfing the web. Nothing real cutting edge. My question is would a G3 ibook be a good choice for this? I have seen decent prices on ebay. I am sure the G4 powerbook is a better machine, but I really don't need that much for a backup. What are your thoughts? I want a notebook for portability too.
