NGS Technologies manufactures the Wallaby optical mouse with a 'kangaroo' system!  This is a 2-in-1 mouse 'system' that can be used with a desktop computer and a laptop, during travelling.

The Wallaby 'kangaroo' mouse has a larger 'shell' that encloses a smaller portable mouse.  When you are using this with a desktop (or not travelling) use the larger shell (that has the smaller one inside).

When travelling, just pop out the inner mouse and take it with you!  Of course, the outer shell will not work without the inner one.

Specifications:

•  2 in 1
