My wishlist:
1. Metal plate.
2. Novatouch stems.
3. 55g domes.
4. Standard 60% ANSI layout.
5. Fully programmable, including Fn layer.
Not as important, but nice to have:
6. Modular controller with 2 options, standard Mini USB and Bluetooth with Mini USB.
And for later models, a silent option and a metal case option....
I think it would sell like hotcakes if the price is right (under $250).
