Sony’s VAIO VGP-BMS77 Mouse is both Bluetooth enabled and rechargeable. The charger uses electromagnetic induction technology so no contacts are involved. The lightweight peripheral adjusts between 800, 1200 and 1600 dpi and has an ergonomic shape, five buttons and a scroll wheel. Expect about almost a month of life on a full charge. Look for the VAIO mouse to ship this week for $99.99.
