2. Lenovo ThinkPad X200 Tablet
Size: 11.6 inches by 10.1 inches
Pros: Although it offers many of the same features as the Dell Latitude XT2, it's significantly cheaper. Like the Latitude, it has a swiveling 12.1-inch screen that allows it to convert from a laptop to a tablet. Lenovo's "palm-rejection technology" makes sure the weight of your hand doesn't register when you're writing on the screen. While the standard model has some touch screen capabilities, you can upgrade to a multitouch panel, which registers two-fingered gestures to pan, zoom, rotate and right click. The "elite" model of the ThinkPad X200, which costs $300 more, features a special screen that can be used in direct sunlight. Like the Dell Latitude, you can boost its security with a fingerprint reader.Cons: Controlling the curser may take some adjustment for users who are new to Lenovo, whose computers use a "TrackPoint" stick rather than the popular touchpad. As with other tablets, heavy users will probably want to upgrade the battery and system memory, making the Lenovo less of a bargain.
