I was going to buy a tablet but found that they are really, really limited in their abilities. It's more like using a large phone than it is like using a small computer.
There are so many things that an Android based device can't do that the only tablet sized device that would work for me was something that actually used a computer based operating system such as the Windows Surface with Win8.
Just be sure you check it all out. I bought the tablet and it only took 1 day to realize I had made a terrible mistake. I returned it to Sam's Club a couple of days later for a full refund.
