I'm interested to see what the system will have to offer in another year. I like the idea of a combined portable/home console.

My two biggest possible concerns are the expected battery life (which isn't too surprising), and the very tiny and cramped looking controllers.

As in, the controllers already look tiny, and instead of spreading out the interface points they're very close together on already limited space.

If you're using both at once, fine. If you're doing some couch co-op with a friend then I think the controllers are going to be annoying.

That means you're probably going to want to buy pro controller, which is extra cost right out of the gate.
