Samsung is expanding its Galaxy Tab tablet line with the brand new Galaxy Tab 2 lineup: a 7.0-inch variant and a 10.1-inch variant.While the smaller tablet was announced a week ago, its big brother, the 10.1 is entirely new. It sports an 1280×800 resolution screen (the 7-inch model has a 1024×600 pixel screen), and the rest of the specs between the two tablets are nearly identical: a 1 GHz dual-core CPU, 1 GB of RAM, a 3-megapixel camera on the back and a VGA one on the front.

The tablets are available as 3G models (meaning HSPA) or as WiFi-only, and they’re both equipped with the latest flavor of Android – 4.0 or Ice Cream Sandwich. The devices should hit the global market in March, starting with the UK, at a yet-unspecified price.Samsung is also announcing a Samsung Galaxy Note 10.1. It’s a big tablet with a stylus.

Aside from bumping up the screen resolution of its LCD to 1280 x 800, from 1024 x 600 on the 7.0, the 10.1 features the same 1Ghz dual-core processor, 1GB of RAM, Bluetooth 3.0 connectivity, front and rear cameras (VGA and 3-megapixels, respectively) and 21Mbps HSPA+ connectivity if you opt for the 3G model instead of WiFi. The 10.1-incher notably comes equipped with a 7,000 mAh battery (up from 4,000 on the 7.0), which will hopefully ensure stamina that's similar to its predecessor. The slate is unsurprisingly loaded with TouchWiz-flavored Ice Cream Sandwich, and will be offered in 16 and 32GB models (expandable by up to 32GB if you supply your own microSD card).
