My Das Keyboard experiment was short lived. I sent it back after a week. The Das Keyboard was good, don't get me wrong, but it just wasn't good enough. I was looking for something that would feel to me like an improvement over the venerable IBM Model M, and it just wasn't. The feel of the Cherry MX Blue keyswitches was good, but not quite the same as the buckling spring Model M keys. And the click of the Cherry MX Blue keys seemed a little higher pitched. At $140 the Das Keyboard was too expensive to keep when I could get a refurbished IBM Model M off eBay for half the price. And so I did. I got a 1991 IBM Model M (1394540). The guy who did the refurbish job made it like new, truly impressive. And with a little "blue cube" USB to PS/2 converter it's working great on my Windows box. The only thing I had to do was to remap some keys so I could add some of the modern functionality we expect from keyboards, restoring the Windows key, menu key, media control keys, and app launching keys.
Ah, the joys of typing on the IBM Model M.
