I have been on the edge of writing "I want one too", mostly because of the blue Enter key, but also because of the programmability. But then I got thinking...
Different caps on different keyboards have different height and profile.
The layout on this board is a bit weird, and may not line up correctly with what you already have.
For instance, the alphanumeric keyboard is one key less wide than on most boards -- you won't even get a full set of alphanumerics for a typical board.
On the Access keyboards, the 2.0 wide keys, such as Backspace, numpad-0 etc are often keys that span two switches: these will fit no other brand keyboard that I know of.
