Samsung launched ultra slim mouse:

Judging from this picture, Samsung’s new ultra slim mouse is as long as the average index finger, and I’ve been told it only measures eight millimeters thick (hence the 8.0 model name).

This pretty in pink mouse comes with a scroll wheel that can operate horizontally and five additional buttons. At present, they’ve only hit the Korean market, although I guarantee they’ll be worldwide in due time.

Not the most comfortable/functional mouse for everyday use, but just like the extra small Kensington wireless mouse, it’d make an excellent travel accessory.
