Dave, you kind of nailed my thoughts. Being a market leader depends on how you define the market. Realize, if I look at it like "TV Connected Apps" then the clear leader would be Microsoft.. hell, forget MediaCenter, Media Room has three cable providers pitching it (AT&T, Charter, SureWest). But we can put that aside.. so 32% of streaming to a TV.. against who? Roku? Boxee?
In fact, I don't even see how they could figure 32%.. if you count a PS3 or an XBOX as a streaming device (and they certainly are; both do Netflix, Vudu, Hulu, etc.) then you're talking about 100M+ shipped units against near nothing for the AppleTV...
The 32% number strikes me as a "we picked a random number and we're sticking with it"
Integration with the TV is a neat idea, but realize, unlike a phone which people live with and can buy at a contract that reduces their upfront cost, you aren't getting that on a TV. It's why 3D TV has had a slow adoption; it's why cheaper large LCD/LED screens get bought quickly.
In another thread, someone showed a graphic of an AppleTV 47" at $1900, and said "compared to all this stuff: TV, BluRay, streamer, etc.) And I thought: ridiculous.. the end user/consumer can go grab a 47" for $499 at any Walmart. Maybe it's not a huge brand, but guess what? MOST of those customers are far more concerned about watching NFL Football or AI in real time vs. showing only streamed content.. and they won't pay more for it.
And since Apple has never issued a product by them in the DVR stream (and frankly, integrating a DVR into a TV, which was tried -once- is a monumental fail), I don't see that either.
I'm sure Apple will roll out a TV product, and I hope that it's inventive and awesome. But their real competitor here isn't "32% of share" It's new XBOXes that integrate with AT&T and SureWest and others to put cable on that can be managed by Kinect. Or it's PS3 owners who can grab streamed content. or Android. The market isn't "well, Creative has an MP3 player.. we can do that better.." It's hundreds of millions of devices already in the hands of customers.
