Barnes and Noble is partnering with Irex Technologies to market an e-reader that can download books over 3G cellular networks. (The bookseller will charge $9.99 for new releases.) The new device differs from the Kindle reader in that its 8.1-inch display functions as a touch screen, operated with a stylus. It also supports a wider range of open e-book formats than the Kindle, such the popular ePub format. Irex hopes to release a color version in 2011.
