1. Wireless Bluetooth Keyboard, Mac OS X v10.4.10 or later, comes with original box and everything that came in the box, including batteries, all documentation, and packaging.
2. Used once, and didn't need it because I have a keyboard on my Macbook.
6. Anywhere in the lower 48, but the shipping is on you. Pickup is free in South-eastern Virginia.
I really didn't need a new keyboard since I already have one that is the same thing on my Macbook. It's in great condition with everything in the box. Nothing has been removed except the keyboard, and I'll throw in some Energizer batteries.
