Microsoft seems to have a keyboard / mouse bundle for every day of the week, but this Wireless Laser Desktop 4000 setup (the Wireless Optical Desktop 4000 is pictured) has some promising buttonry for making your Windows Vista and Windows Live experiences a bit easier. The bundle includes a Wireless Laser Mouse 5000 and a Comfort Curve keyboard, which features keys for zoom, favorites, Windows Gadget, Windows LiveCall and other hot keys. The mouse does the tilt wheel thing for four-way scrolling, and the pair will be retailing in April for $80.
Update: Added the official Laser Desktop 4000 pic, see if you can spot the difference! (Hint, we can't.)
