Best mouse for laptop?

[Izi]

I need a portable but useable mouse. Was thinking one with retractable cord, or bluetooth?

I use a Logitech VX Nano, very comfortable not sure they sell them anymore but i'm sure there is a equivalent model, it comes with a mini usb adapter which fits inside the mouse when you are not using it and a little pouch to put it in as well.
