I got it and it's nice... Unfortunately it can be quirky and lose connection once in a while.
The biggest CON is that there is no easy Scroll function that I can find. Also the thumb pad takes some time to get used to.
that pad is really annoying if youre trying to click and drag... reall, you'd think they would have put a click lock on the software, like you can with regular touchpads... but i found that this device pairs perfectly with WMC, as I think thats what it really was built for.
