It's not the best keyboard for everyone of course, but it's the best for me. Totally awesome personalized keyboard. It's fully supported by my window manager. I don't understand why everyone coming at my desk refuses to write on it…
It's more than 10 years old. It has served me very well, and has been cleaned extensively 3 or 4 times with full disassembly. Here's my personal ritual. Every day when I'm finished working, I cover it from dust with a special cloth. This cloth has been covering my keyboards since I had my first C64, then C128, Amiga and now this one. :-)
