Actually there isn't alot of rebates involved.
MAJOR UPDATE TO MY ABOVE POST!
It appears thatthe prices in my above post refers to XP PRO.
If you get the home edition, the camera package becomes $399, the Memorex
package becomes $49 plus cost of XP home, the networking package becomes $89 plus XP home.
The prices are lower if you buy with XP pro rather than XP home. Deal is not quite as hot now.
