Hi, Am looking for a small, bluetooth mouse with these criteria: 1. Suitable for travel i.e. small - I know some don't like small mice but I don't mind. 2. Bluetooth, not RF-cordless. 3. Relatively ergonomic. 4. Preferably with charge-from-USB ability 5. Smooth use/High resolution - this will be used for editing photos. 6. Actually works well. Any advice most welcome. By the way I've tried the MoGo mouse and while it is cool, I don't think it's ergonomic enough for everyday use. Thanks!
