Bah... I have never heard more nonsense... You can't play FPS with the touch pad... beleive me I have tried... the touchpad takes me 3x longer to do tasks... I reccomend a full sized CORDED (logitech g7 is an exception to this rule) mouse that way you don't have to worry about a transmitter...
My mice of preference are... logitec mx510,518, g5, and the wireless g7...
the g7 which is the mouse I am currently using is just so awsome and the transmitter is about the size of a cruiser micro usb flash drive and the mouse comes with 2 batteries... a single battery seems to last about 4-7 days with average use. the mouse comes with a battery charging station that you can keep at home and let it use power from a powered usbhub... about every 3 days I just swap my batteries in my mouse and that's it... no dealing with those AA batteries...
