I bought a 20" G5 iMac on Amazon.com for $1349 after price break and Amazon rebate (free shipping, and no tax). So that's a great deal for anyone still looking for a G5 iMac. My question is, what software is a "must have" for a Mac?? I already know I want Delicious Library, but what other utilities and apps should I look at, that make life easier? It's been about 6 years since I last owned a Mac and I'm sure a lot has changed.
