This is purely nostalgia. But when I was a kid, Apple released the G4 iMac, and I fell in love. It was the best looking computer I have ever seen. To date, nothing from Apple or anyone else has ever mesmerized me like that machine. They are just gorgeous. I see them on eBay now and then and I've been seriously tempted. Just something to play with, tinker with. Just curious what red flags to look for. I'm looking exclusively at the 20" 1.25GHz model.
