Thin keyboard with big keys

The S510 is a wireless keyboard and mouse combination.  The keyboard is considered a "thin" keyboard, which it is in terms of the overall bulk/thickness of the keyboard, but the keys are full sized instead of being flat.  Do not mistaken this for being like the Sony Vaio or HP thin keyboards.  This is pretty much full sized with a slightly smaller profile.  There are some repositioning of keys (i.e. the page down, right, home, del. etc.) to not have the keyboard as wide, but the number pad is still standard and functional.

The mouse is a standard two button, center scroll mouse.  No side buttons, rollers, 3rd button, etc.  Just regular Joe mouse.  The only thing going for it is it uses an "invisible optic" technology to save power.  I'm not sure what this supposedly does, but I believe that it turns the optical laser guiding light off when not in use as I don't see the typical "red light" when I pick the mouse up. 

The keyboard and mouse are essentially plug-n-play, but if you want the hotkey/shortcuts to work, you need to run the software that came with the keyboard.  With the shortcuts, you can play music (on Windows application, not on keyboard), picture viewer functions, and MS office startups.

What's strange is that the keyboard uses AAA batteries, while the mouse uses AA batteries, so the mouse is a little bulky and not light.  The power thus far has been pretty close to the rated 6 months and this is from a keyboard I use at work, so it's used EVERY DAY.  I would guess with home use, it might last a good nine months.  The "invisible optic" I mentioned earlier on the mouse, along with the night/sleep mode on the keyboard helps to contribute to the savings.
