Hi Just bought a bluetooth logitech mouse (V470). It's cool and fair for what I paid, no complains there. But I got a question about the Bluetooth on Macbooks. I have the Early 2009 model Macbook White. How less is gonna last my battery fully charged with WiFi On and Bluetooth On all time? Obviusly I'm gonna turn off BT when I'm using the trackpad, but just to know. Thanks.
