Summary: One thing Logitech should have stressed was that in order for the USB dongle to work in bluetooth mode, you must HOLD DOWN the connect button AS YOU plug it into a USB port. Otherwise, the dongle will just connect in regular mode, and wont double as a bluetooth receiver. The scrolling on the touch disk may take some time to used to.
Pros: Keyboard is beautiful! Sleek profile, very solid typing experience. This is THE perfect keyboard for an HTPC system. Touch disk is very accurate and great for scrolling through webpages. This is also the one piece of hardware in my HTPC setup that nearly all my friends are impressed by.
Cons: Lack of a designated numpad may be annoying for some. Some people may also dislike the positioning of the pg up/down, del, , home, end keys, which also takes a bit of time to get used to unless your previous keyboard already has an identical layout.
Summary: If you have an HTPC then this keyboard is a must. It works beautifully, the bluetooth works great and best of all it just looks damn beautiful. Many folks have commented on how great it looks. For a normal desktop setup it's still great. The keys feel just right as you type on them. This doesn't have a keypad though which should be noted for basic desktop use.
The mouse or trackpad is the one thing that I hope to see improvement on for future iterations of this product.
Summary: I just bought one of these for my HTPC in the living room. It works ok for that, but I would not recommend this for a "Full use keyboard". It looses connection at times, and the mouse will jump across the screen for no reason at all.
