I want to buy a tablet for streaming tv and movies and watching movies on the go, wifi only. I don't really care about form factor or operating system. It just has to cost $250 or less, and have at least 16 GB of memory. It has to be able to stream from Amazon Instant Video, and HBO GO, so Nexus is out. Any suggestions? I'm thinking about Kindle Fire 7 inch.
