killer app..?? not really
I have aquired and used several keyboards wireless/bluetooth/usb over the years and have found that the Microsoft Comfort Desktop suits me the best. I've had pain in several fingers until I switched to this one. I have a few mice around and the Explorer Wireless mouse works with this set as well.http://www.microsoft.com/hardware/mo...s.aspx?pid=028
Now for the cool part. I have the keyboard/mouse hooked upto a Mac Mini and a spare usb receiver hooked up to a Media Center that's across the room. This allows me to use the same keyboard to control both systems wirelessly (one has to be off at the time but that's not a problem for me.) I basically use the mac mini as a surf/mail machine since I feel it's the ultimate in virus protection for $500.
When this Media Center keyboard comes out, I'll be getting one of them.http://www.microsoft.com/hardware/mo...s.aspx?pid=040
I found the bluetooth keyboard/mouse kind of finicky... not always working and loses the configuration without warning. For my 9300... I use a wired Microsoft Explorer mouse right now.
