On this topic I have 0.5 cents (2 farthings for British history buffs)
I really have to say, I have 2 G3 iMacs (a 600MHz/256MB/40GB/CD-RW unit in Graphite; and a 500MHz/256MB/30GB/DVD-ROM unit in Snow) and they fit in really well with 3 other machines I have from 2000 or 2001 and give me an ability to reminisce about how good the Classic Mac OS really got to be back in 2001, plus they help a Cube, a Power Mac G4 Quicksilver 2001, and also a Pismo PowerBook really satisfy this part of me that's always 12 years old & that refuses to grow up no matter how much better Mac OS X & Intel Macs may happen to be.
That part of me had me assemble a Mac OS 9 tag-team that could run X if I really needed it, but I'd rather just buy an Intel Mac now that the ones I so loved wound up being so obsolete in themselves. I really like how 9 works in a home network, and the iMac G3 duo will be sharing 2 really long-sought & now en route items that will show that although they may be 2 out of 3 CRT-laden Macs that they're still as important for the 12 year old in me as their professional laptop, prosumer desktop, & professional desktop stable mates.
(The other, by the way, is a 128k that I bought and fixed up for basically all the same reasons as the iMac G3s, just time-shifted. In fact I find it takes an iMac G4 to really equal the SE/30, I don't see any iMac G3 really getting that level of power.)
