I've said for years that one of the best ways to do remotes would be with good voice recognition. Apple does a good job with the iPhone/Touch products, but TVs are generally poor to miserable with this stuff.
Instead, I could see browsing sites with a mouse-like remote and some voice commands to bring up websites or recall favorites or history. To browse movies or music by voice would be far quicker...
Maybe
The biggest issues I see with the TVs is that they use cruddy bottom of the line processors which take far to long to respond and are horrendously underwhelming. So, you have your entire audio library availble to your TV... The visual interface may be terrible, and it didn't do a proper import of your songs with cover art from iTunes, so you are looking at a text list. You say 'Browse to M' and it takes ten seconds to jump down to songs starting with the letter M. No, you want to sort by artists... Another ten second wait. You are back at the 'A', so you have another ten second wait to get to 'M' again.
This is where Apple tends to excel in that they provide processing power which generally matches their software requirements so you get a visually appealing interface which responds quickly.
Now, as long as you buy 100% of everything from iTunes and keep a PC up and running with all of your content on it and the PC running iTunes 24/7 you are good with that Apple product.
I have absolutely NO faith that Apple will produce a decent product in their TV after their highly proprietary Apple TV product. I certainly don't see LG as being one up on Apple in this regard.
Darn, I'm such a pessimist on this stuff.
