RCA 10.1” Walmart Special
They are now selling it for $129 and “RCA” (whatever that means) lists it as having a $199 MSRP.
Pop-up ads (e.g., Amazon! and chromebook) are bizarre and extremely unwanted. Even after researching it I still don’t know what VUDU is or why it keeps opening. These are problems I am used to with Android. Maybe I can solve them.

Finally, an affordable Windows tablet. Still waiting for the micro USB cable… (This one has a micro hdmi port instead of a mini hdmi. This appears to be a reason almost everything else has mini—the micro does not stay fastened well and this is a drawback for the “computer.”)
It has to be at least #2 because it is Windows. I know it and prefer it, especially because Android has disappointed me for home use. With a quad-core processor, 1GB RAM, and 16 GB “hard drive” (careful, Windows is bigger than Android) it is a full-fledged computer and 8.1 is Window’s newest. Problem with a video or just about any other function? Import your favorite software from your desktop or laptop computer. It is still $99 at Walmart.
The market has not changed much and for its features it is still probably the best buy out there. 
The 8” screen makes it barely useable in terms of fingers and the many features MS has crammed-in. Do you really want it for your uses? For what, to replace a desktop or laptop? It has bluetooth, HDMI, and USB so that makes it capable of many uses; plus, unlike Android, it easily connects to a Win 7 wifi network.

I don’t know if it is the Android 4.0-ish operating system or what, but this never worked right for me. Admittedly it was at least half my doing but…
The my-doing part includes trying to use a browser (instead of apps) which the device is not really made for. Another mistake is downloading and storing files rather than doing things online; this can be overcome with effort, but it isn’t the easiest way to use these devices. The final thing I didn’t do right was expecting perfect video file playing—size, audio sync, and hiding the screen when connected to a tv all proved to be problems.
That said, this product has been a disappointment.

Conclusions
It is important to consider why you want to use these. Playing around is… fun but. For me it is usually playing videos. I have computers, a camera, and a cell phone for other things. With that said, connectivity, e.g., hdmi and bluetooth, means these tablets can be used in many different ways.
