Yep, they really are a rock-solid machine... My B+W and Yikes served me well for many many years with the only issue being i blew the internal speaker output circuitry in the Yikes a couple of years back by accidentally shorting the pins whilst experimenting with the idea of using a better speaker. That aside, both machines work perfectly aside from the occasional wierdness described earlier in the thread which is just a quirk of this particular logic board architecture... the abomination I got from my old high school in pieces even came back to life after years of mistreatment. My teenage brother also has a dual-CPU Sawtooth still cranking along nicely as well.

For what it's worth, I still used my G4 as a basic web-hack for a bit when my first G5 flaked out... was a bit painful by comparison however I largely attribute that to a little bit of Porsche-syndrome, but moreso to the the comparitive obesity of Tiger as an operating system. I feel it would still have operated comfortably in Panther, but the distinct lack of up to date browsers for anything prior to 10.4 means I didn't really have the option to stay put with 10.3.6, which  is to date still my favourite variant of OSX. As it stood, TenFourFox wouldnt run stabley anyway so I ended up settling for an oldish variant of Camino.
