The absence of a single product makes the Gizmodo list somewhat suspect - where, oh where, is the Microsoft Zune? It is certainly comprable to what Gizmodo is saying about Apple TV, except that Microsoft pushed it hard and is losing a mint on it.
I like my Apple TV fine. There are plenty of things it could be that it isn't, but it is what it is supposed to be - an iPod for your TV. I use it so my kids don't ruin all the DVDs. It's great for that. Plus, I have rented and purchased a few movies online. It's a nice interface for digital content without swapping disks, etc.
I don't think it has been as successful as Apple had originally hoped - but the iPod wasn't an instant hit either. The inability to encode DVDs direct in iTunes is a problem that hinders Apple TV. There is no real way around that since digital movies and digital music are treated differently for digital copyright.
I've long maintained a couple of things about Apple TV - first is that Apple stays in the market to maintain talent and experience in an area that they think may be "the next big thing." By incrementally improving Apple TV, they stay current in the technology and the licensing business so that they will not ever have to start from zero if someone finds a successful model - or if they happen upon it themselves.
Second, Apple's model has long been focused on a single home computer with your media library shared amongst many other devices (iPods and Apple TVs). The problem is that with more people going to laptops or there being multiple computer houses, the need for centralized storage not tied to a specific computer is becoming a necessity. An Apple Home Media Server is the logical answer. Store all your music and video there and let it stream out to your various boxes. The new sharing features in iTunes is a step in that direction, but not a complete one. Apple likes its closed boxes and a Home Media Server without some sort of backup capability is problematic. That is probably something they are trying to wrap their minds around philosophically. They are also trying to figure out how much of a market there is for it and the appropriate price point (hint, something less than a Mac Mini is probably what they are thinking). So my theory is that Apple in 2011 will have some sort of integrated home system for desktops, laptops and TVs. If they can consolidate that home server with Apple TV, that would be ideal. At least if I were in the Apple product marketing division...
