Nook goes HD to face-off with Kindle
Barnes & Noble added two Nooks to the tablet family that have better screens and faster processors. Arriving in October, there's the 7-inch Nook HD (starting at $200 with 8 GB) and the 9-inch Nook HD+ (starting at $270 with 16 GB). They weigh in lighter than the competition and both have slots to add your own memory cards. But neither has a camera.
Gamers will be interested in the Wikipad, 10.1-inch tablet that has a controller dock with two analog sticks, a directional pad and four buttons. It costs $500 and comes out October 31, and retail stores like GameStop are taking preorders. It can download games from the Google Play store as well as Nvidia's Tegra Zone store and the Playstation Mobile Platform.

Go to a friend's profile on Foursquare.com and select notifications to be "Always On." That way you can get pop-ups about what your distant loved ones are doing, live vicariously through someone's vacation, or just have some good ol' fashioned cyber-stalking.
