A few of the other engineers I work with think I'm crazy, but I'd bet $100 that in the next few years, Apple will produce a TV itself and remove this product from the market. The well-known comment in the Jobs biography tipped their hand about a further commitment to TV. Literally everybody I've talked to about it balks at the idea of a full-on Apple tv set. That it's too murky, too much tangling with cable providers…
What would be the difference between say a 21" or 27" iPad with Netflix and HBO Go and iTunes movies and TV shows, and an Apple TV set? We may just wake up a few product cycles from now and realize that the TV isn't necessary anymore.
OK, now make the "TV" a monitor, perhaps with an HDMI input for the cable box.
