The iBook is what got me to switch. I was really taken by the dock and how it magnifies up and down. After playing with it, I really wanted a Mac. I almost got a PowerBook G3, but the seller ended up flaking out on me, so I held out and when the new white iBooks came out, I ran out and bought one.
Since then, I've gotten a G3 800 iBook, which I love and hate at the same time, a blueberry iBook and a tangerine iBook.
The logic board fiasco really changed my opinion of them though
