Being a notebook user I really enjoyed using the Kensington Si750m Notebook Laser Mouse. It features an easily held shape that was very comfortable with extended use. The high resolution laser sensor was quick to react to my pointed movements and the mouse is nicely compact.
You store the receiver inside the mouse and when you place it inside, the mouse automatically turns off to save your batteries. It has 2.4Ghz high-speed performance, and I even used this while gaming, it did wonderful. I didn't test out the range but they claim it has up to 30 feet.
The battery lasted and lasted, they say it should hold about a 6 month charge with only 1 AA. I'm still testing this. Being easy to use and lightweight make it a first choice when I am packing my laptop up to take it with me. I don't fret over the size or weight and it's easily stored in a side pocket of my laptop case. It has a small footprint but that didn't interfere with the use.
