Microsoft PL2 ARC Touch Mouse RVF-00052 Black Touch Scroll BlueTrack Mouse

Pros: I recently used one of these when servicing a client's system. Very nice design, and surprisingly comfortable to use. It wasn't a "cramp" to use like those tiny micro-mice. At first glance it looks like a similar compromise between comfort and portability, but it fits the hand (mine anyway) quite well.

It worked perfectly on a tabletop.

Cons: The price is a bit steep.

Other Thoughts: This mouse is made to be portable. It's flat when not in use or tucked into luggage. It snaps firmly into form when bent into an arch, which also turns it on. Wireless with a very small USB receiver.

I didn't test the receiver's range.

There are lots of cheaper alternatives, but for elegance this can't be beat. It's a sure conversation-starter.

Pros: Simple and easy to set up, very compact and lightweight. Perfect for my Ultra book laptop now a sleeve is all I need to carry what I need in the airport.

Love the way to turn it on and off.

Cons: Batteries do not last the longest on it
