Out with the old and in with the new. Barnes and Noble's nook is quickly supplanting Amazon's Kindle as the must-have e-reader. Not only is it the first e-book device that's 3G and wi-fi enabled, but it also features a digital-lending capability, allowing you to share e-books with your friends for up to 14 days. Better still, that feature is not limited to other nook owners. You can share e-books with any device that has the Barnes & Noble eReader app, which includes PCs, Macs, BlackBerrys and iPhones. Also, the 3.5-in. color touchscreen LCD at the nook's bottom is a snap to navigate.
