Applies when you are mobile, at home the shift to audio via computer wasnt hard.
Did i miss the point ?
You have a very limited universe of people who even use a computer. Fewer still who are willing to do what is needed to play music and watch movies/TV via a computer.
There's a reason that Sony, Panasonic, MS, etc are fighting to get their format to be the standard for DVDs. Because DVD players are what people are going to use. Shoot, I can buy a nice DVD player for under US$100. There isn't a media capable computer for 5 times that. And when is the last time I had my stereo crash? Boot my DVD player?
Don't get me wrong. I love my media abilities. But the rest of my family touches a computer once a week or so. I have friends and one sister who don't even own a computer. I actually have to SPEAK with them!
You'll get their stereo, CD and DVD players out of their house in, oh, 20 years or so.
Seems a lot like the flat screen internet stations for the kitchen of a few years back. Techies were astounded that they didn't catch on.
As for all in one apps, well, I tend to believe that each type of data I have has a particular app that excells at manipulating it. Some apps do an 'ok' job at many things. I don't know many that are excellent at several.
