Main work keyboard: FILCO Majestouch 105-key with browns (very nice), and stacked against the wall for occasional evening use, an AT101W (bleh), Tulip 102-key complicated blue ALPS (very nice), and a Tactile Pro 3 (not sure if like). I've also just added a Realforce 105UB variable weight, which worryingly made my fingers sore -- it's that much stiffer than browns, and rather mushy. I have a Dell rattletrap as well, and a couple of old Latitude D600s with their dreadful keyboards (the whole D series has the same loose, gritty keyboard; the E series keyboard is far better).
For all my grievances against Cherry switches, the more keyboards I try, the more I am convinced that Cherry cannot be beaten.
