I'd like to say I dated someone who resembled this mouse, but I didn't travel in those circles (ok, once) ...
Even Andrew gave up on his Magic Mouse -- and he bleeds Apple.I've used this mouse with my iMac for about seven months. During that time I've scared my kids more than once with a scream of frustration.
This is one of those things that looks beautiful, feels lovely, shows well, but has the heart of Satan. Inevitably, a slight errant motion careens windows about, loses location, or zaps the wrong set of photos.
I beg you, don't buy this mouse. Apple doesn't need the encouragement and they sure don't need the money (believe me, I give them enough).
Yes, I understand the seductive appeal. It's lovely when it works. It does fine with some apps. It's disastrous with other apps, esp. Google apps.
Apple has never made a good mouse. This is no exception. I think this explains why Jobs went to iOS (iPad, iPhone) -- he finally realized he's violently allergic to mice.
Buy a Microsoft mouse. They don't do very many things well, but they make great mice.
I've gone back to using an ancient Microsoft RF mouse with scrollwheel. Maybe I'll buy a Bluetooth mouse, but for now this one works fine.
