I picked up a AT to PS/2 adapter at Fry's today and got the 101 up and running. Great little board, but the verdict is still out as to whether I prefer it over my M. The white Alps keyswitches feel far less worn than the ones on my 102, and the response/sound is much more consistent with what I would expect from a brand new Omnikey board.
If I had one major gripe, it would be that the Ctrl, Alt, and Caps Lock keys are of varying sizes, meaning that although I can remap them, I can't move the actual keys around. Not critical (as I've pretty much got this touch typing thing down), but the perfectionist in me wants to see all the keys in the right places.
Once I find my digital camera I'll get some better pics of this thing. Still can't believe I found an almost-new 101 for a buck.
