MX Air Rechargeable Cordless Air Mouse

It may look something like a NextGen Star Trek phaser, but it’s not, it’s the latest high-end, high-priced wireless mouse from Logitech. For US$150(!) you get a mouse that you can use on your desk or off of it, brandishing it like, well, a phaser. Not really sure how big the demand for such a free wielding input device is, but I guess it’d come into its own as a presentation controller or a Microsoft Media Center remote controller. And speaking of which, it appears to be Windows-only (and Vista-friendly).
