The funny thing was that when I first started collecting Macs, iMac G3s were pretty far down on my list of desirable computers. A lot of the reason for that was memories from high school, where we had a "Mac Lab" with 30 or so of the "five flavor" tray loaders with the stupid compact keyboard and those terrible puck mice(that I'm now working on finding in all the colors

) . I was a Windows guy at the time, and I hated them for the fact that everything seemed so "backwards" and they would crash if looked at cross-eyed. There was also a B&W G3 that I used some for the school newspaper, and it at least took some of the sour taste out of my mouth.
I was given my first two iMacs, a Rev. A Bondi and a late 500mhz Indigo. After getting into them, I realized that they really weren't all that bad and started appreciating how revolutionary they were at the time

One of the things where, IMO, they really fall into their own is for running older "classic" games. I find a CRT advantageous for full screen games since many were 640x480. On an LCD, particularly the higher resolution widescreen ones in iMac G4s and Titanium Powerbooks(as well as LCD Cinema displays), you either have to deal with the game being a tiny window in the middle of the screen or looking like crap because you've scaled the resolution. A CRT is just as happy displaying 640x480 full screen. These make those old full screen games work just like I remember them.
