If you're looking for a full size Android tablet with expandable memory and now access to the entire Google Play store of apps, movies, music and yes even books and magazines, then you really can't go wrong with the NOOK HD+. Here are the cons, no data plan available so it is a wi-fi only device, but that said you can tether it with your smartphone and use that data plan you're already paying for.
I've had mine for a few weeks now and haven't come up with a down side yet, it even has multiple profiles you can set up and make apps and even your library unique to each profile. Great for sharing your tablet and not having to worry about the book you were just reading disappearing from the home screen because the person you shared it with decided to read something else.
I will definitely update this post if I come up with some more cons, and at the moment I'm comparing it to my iPad 2 that I use and haven't signed up for the data plan on it so it is just a wi-fi device for me as well. The iPad has 16GB max capacity and really only about 13GB of that is usable to load up with books, movies and music. The NOOK HD+ came with 16GB at a price of $149, and expandable memory. I happen to have a couple micro SD cards around (8GB, 16GB, and 32GB) not doing anything since I switched to the iPhone and I dropped the 32GB in the NOOK HD+ making it a 48GB device. Total price out the door with a custom cover from B&N was $192 with tax and a recycling fee in California. Even if you buy a micro SD card it would put you at $225 do what I did most likely.
Compare that to the price of an iPad 2 with 32GB or 64GB of memory and I'm sure you'll see the deal I'm talking about. Even the Google Nexus tablet isn't much of deal since you can't expand the memory and it will cost you $200.
