??? What is this thing?! At least don't downgrade you products if you don't upgrade them.
Tab 1- 5mp Camera
Tab 2- 3.15mp Camera, 7000mh Battery
Tab 3- 3.15mp Camera, 6800mh Battery
Same screen resolution, same everything... Just... WHY?
Ok, I see a small upgrade in the CPU department, but nothing worth trading your current Tab...
It should be at least 4-core, 2G ram, Full HD screen, 8MP back lens and 7000mah battery. What's wrong with Samsung these days?
Even Asus makes available sim slot on its tablets, but it only sells in very limited regions. Anyway, Asus is far better option than Samsung in term of specifications, but it is shame to hold tablet without sim slot for today.
