The second generation of Apple TV arrived in early Fall 2010. Like the iPhone and iPad, it’s basically a portal to an Apple-controlled marketplace. Unlike those mobile gadgets, Apple TV has no storage, no Web browser, and few apps. Basically, this is a $99 box that allows you the privilege of renting -- not buying -- current ABC and Fox shows for $.99 and movies from $2.99 and up, in 720p resolution. It earns a few points for supprting YouTube and Netflix streaming, but it’s one of a few dozen devices that do that. Unless you already have a vast library of content downloaded from iTunes, Apple TV is a tough sell.
