EZmouse Packs a Backup So It Never Runs Out of Batteries

They lost their annoying USB cables, but in the process wireless mice also gained an appetite for batteries. Recently they've been put on a power diet, but Digitz's EZmouse goes double deuce on the rechargeable batteries so you never need to hunt down a fresh AAA ever again.

The mouse's main rechargeable battery is good for about four to five weeks of use before it needs to be removed and connected to a USB port on your computer for charging. And to ensure you can keep on wirelessly mousing while the main battery's powering up for two hours, a smaller, non-removable backup provides up to three days of additional use. When the main battery is topped off and re-inserted into the $50 mouse, the backup then automatically recharges itself so it's ready for the next time it's called upon. A feature I wouldn't mind seeing added to digital cameras and other devices with removable rechargeable batteries.
