So I've had my Logitech MX Anywhere for a while. It's got their any-surface technology in it, so it's a great mouse. I'm tired of the silly Logitech Dongle, and want to switch to a mouse that uses bluetooth. Anyone have any recommendations as to any-surface (particularly glass) mice that are bluetooth? I know Kensington has one, Microsoft too, and a few others. What do you recommend? Requirements: - works on glass (and any other surfaces) - bluetooth\no dongle. - used for traveling on macbook air Thanks!
