For the price, $149.99 which I paid for my 16GB Nook HD+, this device is hard to beat.  The display sports a very good picture--one of the best I have seen--and the OS is pretty smooth with only some occasional lag, which might be an issue with certain apps.  When I opened my Nook and fired it up, Google Play had not been installed.  After a quick software update, Play appeared which allows me to download a great deal of Android apps onto this device.  I have since added all the apps which I consider to be essential, for me, and all of them work nicely.  As for the feel/design, it's nice.  The tablet isn't too heavy or too light, and all the buttons are placed nicely for ease of access.  Even better, this unit has a micro SD slot to expand memory.  The only thing missing from the last tablet I had, that I can tell, is the camera--and honestly, I don't care about that.  Cameras typically aren't that great on tablets anyway.
