The WinBook TW700 is a very inexpensive 7" tablet that runs a full version of Windows 8.1. It has 16GB of internal storage, with the option to expand that to 64GB of storage with an SD card. It has 1GB of RAM, an Intel BayTrail 1.33 Ghz Quad-Core CPU, and a 7 inch 1280x800 IPS display.
The WinBook TW700's full size USB 2.0 port and a micro USB port. This makes it possible to plug in a keyboard and mouse, and turn it into a more traditional Windows machine. It also features a micro HDMI port so you can connect it to a TV or monitor.
The only real major negative to this tablet is the front and rear cameras. They are very low quality, but the front facing camera is good enough to at least have a low quality Skype video conversation.
The WinBook TW700 is available now from MicroCenter.com for just $59.99. It also comes with a year subscription to Office 365. This subscription alone normally costs $69.99.
