1. Apple iPad 2
The iPad remains the king of the category and, even with the invasion of an army of challengers, the iPad will retain a commanding market share lead when we get to the end of 2011. It still has too many factors in its favor: dead-simple usability, long battery life, a massive catalog of apps, and a respectable price. The last factor might be the most important. The iPad's rivals have had a very hard time beating the iPad's price tag while offering a comparable experience. The iPad 2 doesn't offer any revolutionary changes over the original iPad. It's thinner and lighter, has an upgraded processor and display, and adds front and rear cameras. It's a nice refinement, and with its big advantages in apps and entertainment, it easily has enough value to keep it at the top of this list -- even for business users, who want the apps for business tasks and the games and entertainment for plane rides (and to distract the kids once in a while).
