I got this mouse to be able to use the BlueTooth radio embedded in my work laptop. It's small enough to carry around, yet very comfortable for daily use. Not that while I ordered from a page that showed the blue model, I received the white "for Macs" model - doesn't really matter, they are the same.
Connection to the computer was quite simple as I use Ubuntu - in XP it was a little more complicated, but finally it worked and has been ever since. As soon as the computer is booted up (in both OSes), the mouse gets recognized and works; immediately in the case of XP, and after logon with Linux, which is normal as the BlueTooth stack is loaded after logging in your account.
The V470 is very precise, works on most surfaces, even some which are quite reflective, but not on glass evidently. Battery life should be good, my girlfriend has a VX Nano which has been running for over a year with the same AAs in it. The V470 also comes with a small pouch for storage.
The 0only "con" is that it goes to sleep regularly. After reading for some time, you move it and it doesn't move the cursor immediately. It wakes up, and then moves it, which makes for jerky operation when that happens. I got used to it, and it doesn't bother me anymore. My guess is that battery life is protected that way.
A very good buy IMHO!
