Awesome keyboard. I really like this keyboard. Very comfortable, good design, cool looks, key sensitivity feels good. I've even used it for gaming with no problems.
The looks of the programmable keys is really cool, and I like the gloss, blends in with my monitor.
Wireless range is great as long is nothing is in the way.
Weaknesses:
I'm not too crazy about the mouse. It's ok, but doesn't seem as good as the keyboard. I'm thinking about grabbing the Microsoft X8 mouse to go with this. I don't use the crazy amount of programmable keys on a gaming keyboard, so this keyboard is perfect for me, even for gaming. (And there is not too many wireless gaming keyboards to choose from)
USB transiever needs to be non-obstructed.
Summary:
Great comfortable keyboard, good for typing, multimedia use, and non-hardcore gaming. (I use it for BF3 and it's fine)
Get it on a good sale, and it's worth it for the keyboard alone.
