Other than the Logitech v270 there seems to be such a small selection of BT Mice on the market. I want to add to my Powerbook/Apple Wireless Keyboard and would never buy a mouse with NO scoll wheel, just seems like it would not help me at all. A 1 button mouse=slowed productivity. I'm sure as soon as I drop $40-50 on a BT mouse the next day apple will release a BT Mighty Mouse and it will cost $99. Searches on Amazon for BT mice show many no-name manafactuers and brands I have never ever heard of, what to do?
