The TAB3 7 starts at $129, which gets you a 7-inch 1,024 x 600 IPS display, a 1GHz quad-core MediaTek processor, 1GB of RAM, 16GB of storage (expandable by MicroSD), LTE connectivity, a 5-megapixel rear camera and a 2-megapixel webcam.
The TAB3 8 starts from $99, comes with a 1,280 x 800 8-inch IPS display, and everything else the TAB3 7 has apart from LTE connectivity. For that, you'll have to pay an extra $50 for the $149 LTE model.
The TAB3 10 Business starts from $199. For that price you'll get a 1080p IPS display, a 1.3GHz quad-core MediaTek, 2GB of RAM, 32GB of storage (expandable, of course, by MicroSD), Android 6.0 with Android for Work, dual-band AC WiFi, an 8-megapixel camera, and a 5-megapixel webcam. Like the Tab3 8, you can add $50 for LTE connectivity, but there's also a $299 model that adds more RAM (3GB) and storage (64GB).
Because it's for business people, and business people hate colors and joy, the TAB3 10 comes in black. It's also IP52 splash-proof, because business people often spill coffee on their tablets. And it has Face Unlock! We assume because business people are far too busy spilling their coffee and hating colors to mess around with unlock patterns.
The TAB3 10 Business will hit stores in July 2016, which the TAB3 7 and 8 will be available in June.
