The world of tablets keeps growing. New entries include the Nook HD and HD-plus, the iPad Mini, and the Surface - Microsoft's first tablet. Consumer Reports tests to find the best. While the top ones all have something to offer, there are big differences. For example, the 500-dollar Surface has a superb 10-inch screen plus a handy stand, and you can get a cover with a built-in keyboard. However, when it comes to content, Microsoft has a way to go. "Windows tablets lack access to the big content selection from Apple or the Android Marketplace, or even the Amazon and Barnes and Noble content offerings." Size is another important consideration - the 7-point-8-inch i-Pad Mini is Apple's first smaller tablet, competing with other small tablets like the Barnes and Noble Nook HD and Kindle Fire HD from Amazon. Consumer Reports finds in many ways the Mini is every bit as good as the bigger i-Pads. The screen offers crisp text, optimal photo viewing, and good sound. The 330-dollar i-Pad Mini is also light, making it extra portable. But for 200 dollars, the Barnes and Noble Nook HD is well worth considering. Sharp text that fills the 7-inch screen makes reading a pleasure. However, the larger 9-inch Nook H-D-plus is a better choice if you're a magazine lover. It starts at 270 dollars. Paul Reynolds "The iPad still offers the most content, and its screen's a little bigger than the Nook HD+. But at 500 dollars and up, it costs almost twice as much." Consumer Reports says no matter what your priorities are, there's never been a better selection of tablets to choose from. "
