I haven't taken apart an alps switch before, but yes, PCB mounted cherry switches are easy to take apart. there are 4 pieces, the bottom of housing which is soldered to the PCB, the spring, the stem, and the top of the housing.
All cherry switches use the same bottom and top housing. They only vary in the spring and the stem shape. To replace a PCB mounted cherry switch, you can pry the top and bottom of the housing apart, change springs or change stems, and voila your old keyboard has different switches.
The presence of LED's makes this not possible without desoldering the LED's first. Plate mounted cherry switches are more difficult to switch, they need to be desoldered at the base.
Skcheng: I find the TG3/deck 82 key keyboard to be very nice in size (about the same size as a HHKB) allowing for good midline mouse position. This keyboard however is of small size, some might find the small sized enter / small sized backspace / small sized tab / small sized left shift to be cramped. The form factor is very similar to the ricercar SPOS which I liked.
The backlighting is good for bling. But the more I think about it I don't think I want LED lights shooting into my eyes all the time. Cherry blacks, good for gaming and small amount of typing.
PS: The Ice is sold. Congrats to whoever got it, be sure to post a review.
Are Cherries like Alps in that you can just swap the guts of the switch without desoldering it?
