Samsung Galaxy Tab
Last updated: Apr 12th, 2011.

The Samsung Galaxy Tab is the first high end tablet released with the Android operating system. It has a 7 inch capacitive touchscreen, 1Ghz processor, and Android 2.2 with the Samsung TouchWiz UI.
Being the first real competitor to the iPad, the Galaxy Tab has fell to a lot of scrutiny, but has been a very popular device since it's release. Also, being released on all 4 of the major US carriers has definitely helped this tablet become a force to be contended with.
