Harry, where did you find the ALPS Minitouch board?
***EDIT*** I just noticed you said "GH" version.
SPeaking of feel and breaking in, the earlier SIIG rubber dome board has a softer feel. The replacement one (with unmistakeable BTC label on the back next to the SIIG one) is stiffer and takes a few weeks to break in.
I have been using these boards at work every day since they first came out. They last about five years. The SIIG-branded model has a five-year warranty. The only real complaint I have is the arrow key arrangement, but we Emacs and vi users don't use arrow keys that much.
In stores now is a mini, laptop-style keyboard sold by SIIG which I won't be using.
The BTC 5100C model comes with a PS/2 port. Yow!!
