This tablet runs Android 4.4 on a quad-core 1.6GHz MediaTek MT8127 CPU with 1GB RAM and a nominal 16GB internal storage. It sports a low quality 7" display with a screen resolution of 1024 x 600, and it also has a VGA resolution camera, an HDMI port, Wifi, Bluetooth, and speakers (plural).
The NX700QC16G measures 7.59" x 0.37" x 4.41", and comes with a 3Ah battery. It runs a full version of Android, including Google Play. It ships with a number of apps, including Vudu and Walmart.com, Cloudlink, Flixster, Net Nanny, and Nook for Android.
All in all, it's not a bad tablet for $79 but I don't think you should buy it. That is a cheap price, but even at that price point there are better choices.
For example, as I pointed out in my budget tablet buying guide you can find the Hisense Sero 7 Pro for only $78 at Amazon. That is a refurb and not a new unit, but given the specs I still think it is a better value.
While I am wary of buying refurbs, Hisense is one of those brands I would risk buying. To put it another way, I have higher confidence in a refurbished Sero 7 Pro than in the Nextbook tablet which just launched.
