If Apple truly is getting into the tv market they will have a hard time. The tv market is different in quite a few substantial ways from the computer market:
1. The buyers are (generally) different
2. This is a high volume low yield race to the bottom
3. Build quality actually hurts in some ways (More on that in a sec)
The reason they did well with the ipod, ipad and iphone was ease of use, build quality, and a new experience. All of that can be changed up on the computer world, while none of it really matters for tvs.
For starters, it's a tv. It sits there. It doesn't matter what the build quality is as long as it's thin and doesn't catch on fire.
In fact, bad build quality is helpful in a lot of ways, the cheap plastic they use helps make these things wall mountable. If you used aluminum in a 55" tv you wouldn't have much of a chance of wall mounting it.
For another, you can make smart tvs, but really, in the end it's a tv. The biggest changes are resolution, and picture quality. There's not much to work with.
I'm sure many fanboys will disagree, but if Apple goes into the tv business with $5000 55" tvs they will fail.
Ah silly person...you just don't get it. You will..you will...
Everything you just said here could have been applied to the iPhone and it was. And Apple destroyed all those preconceived notions.
Apple disrupts. All your points are what you view a TV and it's experience in the here and now.
