Yesterday, I went to the Apple Store, intent on buying a Magic Mouse. I went, then walked out empty handed because I wasn't thrilled on how the mouse fit in my hand. Maybe it's something i could get used to, but the fact that there are also only two buttons. That got me thinking to getting a used Bluetooth Mighty Mouse. Are the ergonomics any better on that than the magic mouse? Is the scroll ball really a pain? Also, what are some other good options for Mac Bluetooh mice? I'm lost when it comes to searching for a good one. Thanks.
