I think it could be lovely.
I've been looking for ages for a decent bluetooth mini-keyboard. All the ones I could find are maxi sizes.
The Happy Hacker one is nice but it's wired. I brought the old BT Apple keyboard, but returned it after a week as I didn't like the feel.
I never use the numberpad nowadays. I used to use it extensively for playing Angband and other dungeon crawlers but I'm trying to do less of that now
I have two of the famous IBM models aka "the best keyboard evar" but they're just too big and heavy now. I liked the ThinkPad keyboards, and I LOVE my powerbook keyboard (after disabling the caps lock key which i accidentally press all the time).
Only problem with the new Apple keyboard is it's a bit expensive - 50 quid yikes! RSI and body posture demands that I get it tho. Looking forwards to trying it out at Apple Regent Street soon.
