On paper at least, the Android 4.1 (Jelly Bean) model is not so different from its predecessor, the $250 Galaxy Tab 2.
There is a 7-inch 1024 x 600 resolution display, dual-facing cameras, 1GB of RAM and a slot for a microSD card (which can accommodate up to 64GB of memory, an improvement from 32GB on the previous model).
That is where the similarities end though, with the Galaxy Tab 3 packing a more powerful 1.2GHz dual-core processor (compared to a dual-core 1GHz chipset on the Galaxy Tab 2) and now offering an option for 16GB or 8GB of internal storage. The device also has a smaller bezel than the Galaxy Tab 2 as well as slightly smaller dimensions.
Samsung says that the WiFi-only version will come to market early next month, before being followed by a 3G model, which can also make phone calls, at some point in June.
