I'm using an IBM R40 (Pentium M 1.4Ghz) with Debian and Squeak. Squeak 
seems to run pretty fast subjectively - when I've worked with people 
using Macs, it seems that some things (redraw while debugging, in 
particular), are happening much, much slower there than on my machine.

For what its worth,

0 tinyBenchmarks ->
  '232304900 bytecodes/sec; 7018937 sends/sec'
   '225352112 bytecodes/sec; 7028070 sends/sec'
  '230838593 bytecodes/sec; 6830576 sends/sec'

(hmm, that seems almost twice as fast at bytecodes/sec as the Dell 
reported, interesting)

Caveats -
1. My machines battery is completely shot, 1.5 years after I started 
using it (though friends of mine with similar setups have had better luck).
2. Squeak and Skype apparently don't play nicely with the sound daemons 
(on KDE), so when Squeak is on, it locks the sound, and then skype 
behaves weirdly.
