The version of the tablet being released today has Wi-Fi only connectivity. It does have some beastly specs, with a 2560 x 1600 resolution on the 10.1 inch glass. The slab is powered by a Samsung Exynos 5 Octa CPU with 3GB of RAM and an 8MP rear camera. If you're looking to find this device, your best bet is to check out Best Buy and Best Buy Mobile, BestBuy.com, Amazon, PC Richard's, Fry's, Tiger Direct, Walmart and Samsung.com. No, your search does not have to be in that exact order.
