A Nexus 4. As I said, my criteria are that I can run my own software on it without having to go through some intermediary, and I am able to replace the operating system if I would like. I would prefer a fully free software stack, but I realize that that's not always possible, so I like to support the next best thing. Traditional consoles have always been so hacking unfriendly that I have refused to buy them. Just so you know, a Nexus One was the first cell phone I ever bought; it was the first that I considered free enough (and capable enough; the Dream/G1 was just a little too clunky for me to consider it particularly useful).
