In a recent set of comments we spoke about adult children and when it is that they start to get the high-end "itch". In my experience, it starts in their 30's and extends into the 40's.
The desire to have something better, a step above the status quo, begins at these ages and it occurs in the majority of the population from what I can tell.
Better car, better house, better stereo system.
The holdback issue is size and ease of use - not price. I can tell you right now if it ain't wireless, small, room filling and awesome, it isn't going to be a winner for future generations.
A constant theme you'll read from me in these posts is the need for the high-end to be pulled into the 21st century. Some will go willingly, some kicking and screaming, some not at all.
I am here to tell you small, powerful, room filling and wireless are possible. The best system you've ever heard can be replicated in a much more acceptable package if the right designers get it together and aim for it.
We can encourage high-end designers to work towards it. We are.
