Logitech introduced its neww iPhone 3GS because of the compass! We're aiming for release after summer, but we deply frictionless scroll wheel, laser tracking and a low battery indicator.

All in all, it provides some basic conveniences that you might not find in a standard notebook mouse. Cordless is always nice and zipping through huge documents and web pages with a single flip of the scroll wheel could definitely be helpful while working on the road. If you agree, the M555b will be available later this month for $50. [Logitech]
