Yesterday, my local Apple store finally got the wireless keyboard in stock. I have the usb slim keyboard on my PC and love the feel and action of the keys, so I wanted to get the wireless model for my Dell Linux Box. I ended up using my $100 iPhone early buyer credit to purchase it.
The keyboard works great. I was able to get it to work with Ubuntu 7.04 Fiesty Fawn along with the Bluetooth Wireless Mighty Mouse (How-to here). The eject key even opens the CD tray in Linux. The keyboard battery compartment opens with a coin and takes 3 AA batteries and boasts very good battery life (About 7 months). Overall this is the best small keyboard I have ever used.
The keyboard goes for $79.00 and is available at the Apple Store online here.
Update 10/12/2007:
I later tried to get it working with Windows XP but had no luck.
XP would detect the keyboard, but didn’t let me enter a pin to connect to it.
