I disagree. Does it have, or potentially have a full OS? Sure. So do tons of embedded devices (e.g. home routers), but I bet many of those devices would void your support if you "jail broke" them.

It's meant to be a device, regardless of what you think it's capable of. There is a reason nerds/geeks are never consulted by sales. If you don't like the device then don't buy it. I'm sure plenty of nerds will be out there saying "but! Lets make it a whole computer! Then we'll kill apple!". Buy one of their devices to go with your Android phone. Don't mind all the people laughing as you trudge your way through using them.
