Re: I'd agree - no (little) innovation
Sadly, what I mostly read in the above posts is people saying that because THEY can't think of anything that's wrong with the current typical computer, then there's no need for innovation.
But that's a lack of imagination and a blind acceptance of the status quo.
What a load of rot. The converse is simply valuing innovation for its own sake, which is no better an argument, and indeed arguably worse, since it exchanges a situation that can be evaluated with one that cannot be.
I, and I expect everyone else here, am perfectly capable of imagining all sorts of "innovations" for personal computers. That doesn't mean I find any of them desirable. And dismissing Cador's empty complaint about a lack of innovation is neither an endorsement of the status quo nor blind: it's simply a refusal to consider change a good-in-itself, and it's based on a wealth of experience with change in the PC industry and elsewhere.
Nothing on your list is particularly innovative, by the way; it's all been done before, as you admit. If any of it is desirable, what's needed is incremental improvement. Certainly it's possible that something radically new could be done in one of those areas, but there's no reason to believe a priori that there's a significant chance of that, or that the result would be particularly valuable to a significant part of the market.
 None of it interests me much, frankly - which is not to say it's not of interest to anyone, but it's certainly not of interest to everyone. And some of it, particularly the home-automation stuff, I think is a terrible idea.
