Pros: Excellent feel and quality, as I said much better than expected. Work perfect with my Linux box and the mouse has a few time saving features. It only has a few media buttons, but the all work perfectly.
Pros: Small, just what I wanted for controlling my laptop attached to my TV.
Cons: The keyboard will only work if I am within three feet of the receiver. As I move away, the cursor gets more and more erratic and then stops moving when I am six feet away. It needs to work reliably within twelve feet which is well within the 33-foot range advertised. I replaced the batteries but this had no affect.
Summary: The fact that the keyboard has a slot on the bottom to stow the receiver when not in use is a bonus, so I am not removing any eggs for the fact that it doesn't hold the receiver as well as it should. It is fairly easy for the receiver to fall out of the keyboard, but that is only a concern if the keyboard travels between computers.
Pros: I use this with a cheap 16-port KVM to control 16 computers wirelessly from my desk (imaging station). Having the keyboard and touchpad in one unit makes it much easier to walk around or lean back in my chair while working on a computer. I have not had to click the "connect" buttons on the receiver and keyboard as is so common with most other wireless keyboards/mice. It connects immediately and can be used to enter a computer's BIOS.
Cons: I wish there were no Numlock/10-key overlay. Yes, I know this can be disabled in the BIOS but I don't want to do this for each of 16 computers, especially since the 16 computers are replaced frequently. If there were a switch to force numlock off (override computer setting) I would be happy. I don't know anyone who actually uses the 10-key overlay pad on a laptop.
Summary: It would be nice to have a mute button. However, you can use F8 in Windows Media Center to mute the sound.
Pros: Perfect size for an HTPC keyboard. Almost exactly the same size as the keyboard on my HP EliteBook 8530w laptop, which is one of the better laptop keyboards I've ever used. I have large hands and this keyboard works perfect for me.
Cons: It would be nice to have some programmable buttons in addition to the Home, Search, Favorites, and E-mail buttons (these are configurable in Windows).
Pros: Blackspire: You can change the default setting for the NUMLOCK key in your bios settings; it doesn't have anything to do with the keyboard. Most motherboards have the NUMLOCK on by default because typical keyboards have separate number and alpha keys, but this keyboard doesn't (to save space).
Pros: Good range (see note below), well-built, good touch to keys, touchpad works great. Nice features for using without a mouse, such as dragging two fingers to scroll. I don't know how, but the BIOS recognizes this as a keyboard even before the drivers have been loaded, so you can use the keyboard to edit BIOS settings :) Great addition to a HTPC.
Cons: The reception didn't seem to be very good with the dongle mounted in the back of the HTPC and inside my rack, so I used a USB extender to move the dongle along side the case, and now it works fine.
