"The march of mouse progress apparently never stops, and Microsoft just announce a pair of new ones to drive that point home. The Wireless Laser Mouse 6000 (after the break) is the more portable one of the bunch, with a snap-in 2.4GHz USB receiver packed inside a desktop-sized laser mouse. The Wireless Laser Mouse 7000 (pictured) sacrifices a bit of portability for a rechargeable batteries -- with a horizontal charging dock to host the mouse when times are rough and juice is scarce. Both mice include Microsoft's HD Lasers and a few Vista-friendly buttons. You can pick them up in March fo $50 and $70, respectively."^^<http://www.w3.org/2001/XMLSchema#string>
