I like the original PS2 keyboards, as well as the PS2 mini keyboards for desktop computers, but some of the 1990's era IBM keyboards that have the rubber mebrane in lieu of the mechanical springs are ok, because they are still solid in their own right.
I liked the original IBM thinkpad keyboards from the late 1990's to early 2K's as they were really solid as well. --I'm currently using a small Panasonic Toughbook to type this, and it's decent enough, if a bit small, as I have very long fingers.
