I purchased a Microsoft "intellitype pro" keyboard and mouse that I saw on special offer in Maplins on the 17th July 2007.
Neither keyboard nor mouse uses the rechargeable batteries but standard AA & AAA alkaline batteries. Same batteries are in situ and a quick check of the power levels indicate "good".
I can't think of anything I dislike about wireless K & M, no wires, faultless performance and excellent battery life on a system that is used and left on everyday.
Went a step further just before Christmas and bought a wireless router, brilliant!
I am able to lie in bed with my laptop and simultaneously listen to the radio (streaming), surf the web and print a word document without any problem whatsoever.
There is no way back once you have tasted the freedom that wireless gives you, a bit like broadband and dial up.
I thought it would be fun to demonstrate the flexibility that the wireless router gives you so I am typing this on my laptop whilst sitting on the loo in the process of getting rid of a few pounds in weight
