It is my understanding, that a 1.4 G4 is a pretty good speed/chip.
We have one guy in the office who just won't let the mac go, won't even upgrade to OSX, of course he is on a blue G3 so that's pretty shitty to begin with.

I think he is going to upgrade to one of these, at least then I can stop hearing him get upset every time it dies. The old one only has a 6 gig drive in it.
