Staples literally sold millions of the Nobis NB7850S, a 7.75" tablet with 1024x768 screen and a sturdy aluminum back. Not at all a flyweight piece of junk.

Yet it's gotten zero attention from the Android dev and hacking community, and no updates from its manufacturer. However they did replace a battery for free when I sent them pictures of how it inflated and popped the back off.

It has Android 4.4 Firmware version 4.5_20140324 Kernel version 3.3.0 Build number A31S_Q791_Q7911L3B2C_79D4.20140510 Processor QuadCore-A31Series
