Barnes & Noble's device -- the Nook -- will hit shelves at 2,500 stores as soon as October 24, while Borders's Kobo will rock into as many U.S. shops next week. The Nook will be available in two models -- Nook 3G as well as Nook Wi-Fi -- and many stores will have e-reading areas where folks can get their hands on the goods.
These two devices join Apple's iPad, which recently arrived in Wal-Mart stores.
