Microsoft’s new Mobile Memory Mouse 8000 is a well-designed, full-featured, and — at US$100 — expensive input device.
This wireless mouse worked great on all desktop surfaces; it even worked on rough or unusual surfaces such as glass and the keys of a keyboard.
Powered by a rechargeable nickel-metal hydride battery, it can charge through a small cable that latches magnetically from the mouse to a 2.4-GHz USB receiver that also doubles as a 1GB flash drive. (You can connect the mouse via Bluetooth, too.)
Business travelers will appreciate the flexibility this mouse offers; other people will find its price too high.
