Ask HN: What are good compact keyboards for programming?

Lately I HATE the arrows/home/end etc keys on the right and want something where either they are removed, or shifted to the left hand. I'd rather have my right hand move my mouse, but for now I'm using the mouse on the left.

I do this because of shoulder pains caused by the mouse on the right.

I tried the Genius i200 keyboard after I saw the reviews on Amazon, but the keys are very hard to press, so I'm probably going to return it.
