I recently picked up a VX Nano for my EEE PC and have started using it on my desktop, I love it! I'm really impressed by the features and performance of the VX Nano. I haven't used a wireless mouse in a few years and the technology seems to have really come a long way since then, unfortunately the VX Nano is not comfortable for the amount of time I spend gaming on my desktop so I'm considering upgrading my Logitech G5 to the G7. How many [H] users are gaming with a G7? What kind of battery life can I expect while playing FPS games? Any problems with fast movement on black mouse surfaces?
