Hardware & Performance
The Panasonic Toughpad JT-B1 runs Android 4.0 Ice Cream Sandwich and comes with a 7-inch, 1024 by 600 pixel screen. Under the hood we see a TI OMAP4460 dual-core system-on-a-chip running at 1.5GHz. There's also a gig of RAM and 16GB of storage tucked in there, in addition to a 13-megapixel main camera on the back and a 1.3MP snapper on the front side. All of the usual connectivity features come standard.
