aye, i love this mouse, but the keyboard? its mediocre. its a nice keyboard, but i've found i few things about it i don't really like:
a) sometimes the macro program freezes on boot.
b) the keyboard always has to be in the same usb no matter what, or you will have to re install the drivers
c) the media keys only work if you have the media program open and in focus, thus sorta defeating the purpose of them for me.
d) the macro program doesn't work on 64 bit xp...but i see u have vista so that doesn't really matter, there are vista drivers for it.
oh and done ever remove all the keys to clean it...i did and now my left shift key doesn't work properly.
