It should work but provided the mouse supports the settings of this keyboard, check out the ms devices micro-site for this before going ahead.
I bought this keyboard recently, but then I find out that this keyboard is sold in another bundle with a mouse. But of course I wouldn't buy the same keyboard just to get the mouse in the bundle. Yet I'd still like to ask, can the mouse be bought separately and work with the existing wireless receiver of the keyboard? If it is possible what model should I buy?
Real experiences will be most appreciated.
