I have the black edition, and I'm really happy with it. The battery charge holds for a long time, so recharge isn't required that often (it of course depends on usage). I really like the low profile keys, which makes me able to relax my hands better when typing. I do however experience a rare double input registration when typing. Haven't figured out why yet.

On one hand it is a very comfortable, beautiful keyboard, and wireless has worked flawlessly. On the other hand, 2 blue leds have failed, so currently dealing with warranty.
