Caps being backspace is the first thing I miss when using QWERTY. Hardly even realize how much I use it (I make a lot of mistakes) until using a QWERTY keyboard.

I need to set up colemak for my console, I have been lazy. I don't use the console much but it's a bit of a headache when I do since I have forgotten the QWERTY layout (I have stickers on my keys).

I recently came across the Datadesk SmartBoard. I haven't used it, but it looks like it is well thought out. I just wish it had more keys for the thumbs.

Just look at the page linked to, it's right there. Salient points:

I also see 15 F-keys, but on the other hand the PrtSc–Break key block merged into the Num block (with RightShift) which I don't like so much even if those are oddball keys nowadays: I use them for shortcuts. It's a minor thing though.

Since I've taken to modding keyboards for Colemak I'm not a fan of this keyboards' individually shaped keys from that particular perspective. You cannot build the SmartBoard into a physical Colemak except by relabeling the keys (using stickers for instance). From an ergonomic point of view however, this board should be well ahead of the Microsoft Natural which keeps the stupid key row staggering stemming from the days of mechanical typewriters.

It's a very good board to type on from the looks of it, but somewhat lacking in completeness and also expensive of course.
