I said it years ago when these ridiculous TV rumors started and I'll say it again. There's nothing a physical TV will solve that

TV wouldn't/couldn't.
If Apple wants to tackle interface, they need to start posturing the

TV device as the hub in which to plug all your tertiary devices. If your cable box, DVD/Blu-Ray, game consoles and speaker system plugged into the

TV, THEN into your TV, Apple can owns the entire user-experience... and can do it on every existing TV, without trying to convince people to throw out their existing TVs for something so trite at user-experience. Remember, a TV is something that doesn't have a short lifespan, like phones and laptops. Adoption of a new TV is a hard sell for many people.
If Apple wants to redefine content-providing (which I'm absolutely 100% confident they do), there aren't going to be any hardware limitations that an Apple-branded TV will solve.
I'm certain Apple has TESTED the idea of an Apple-branded TV in their labs (and I think this is what Woz is referring to), but there's very little (if anything at all) that Apple can do to improve the bread-and-butter TV.
