Why should I get (or not get) a nexus 7?

I am looking at picking up a nexus 7 (2013), but before I do what should I know? What are some things that perhaps haven't been covered in most reviews, or something that you noticed using one? I am looking for both good and bad here, just to help me round out my choice. Sorry if this has been covered in the forums before, and thanks in advance for the help.

UPDATE:

What do you use your nexus for? What is it best and worst at doing?
