The Galaxy Tab 3 (7.0) specs include a 7.0 inch display with a 600 by 1024 pixel resolution, up to 16GB of internal storage which can be expanded through microSD, a 3.2 megapixel camera, optional 3G connectivity, a secondary camera for video calls and a 1.2GHz dual-core processor with 1GB of RAM.
The 7 inch Galaxy Tab 3 may not be a worthy upgrade for Galaxy Tab 2 users, but maybe a great entry point for someone looking for a good entry-point into the Android tablet world.
