Wireless Keyboard?

What si the function or reason for a wireless keybaord for the SMP?

What I’d liek to be able to do is a SEARCH for all movies movies/TV/Photos and MP3.

Possible? If so, how to setup on the SMP?

A keyboard will make it much easier to enter search terms and other text entry on the SMP.  Any wireless PC keyboard that uses a USB dongle receiver should work.  If you are already using both USB plugs for hard drives a USB splitter box will work for a keyboard and a hard drive (but not for 2 hard drives) into one USB plug on the SMP.
