I was confused by this too.
What envelope is the "open PC" pushing exactly?
Sure, as a box of parts, you can plug in newer shiny parts.
But as a consumer product, the rate of innovation has almost ground to a halt.
No PC manufacturer is capable on software innovation. And so the progress of the platform is shackled to Microsoft. - And Microsoft's rate of innovation (in the PC space) has become really really slow.
There's no innovation in that space, which is why the PC market seems to be dead on its feet. A clear sign of this death, is that manufacturers don't seem to be able to make more than a 5% margin.
What was the big PC announcement at CES? Oh yeah. There wasn't one!

You see there is a fundamental mental difference here of what a computer is.
You, and I guess many Apple people (and some PC people) see a computer in the same was they see a Microwave, a Toaster, a Fridge, a HiFi, a TV.
It's an item made by a company that they buy and it works, when they don't want it, they sell the item on and buy a new one. This seems to be the Apple way, and it the way with thing like Laptop and Phones etc.
To, me, that's not a computer, that's like a consumer item, an appliance.
For me, in my mind a computer is a collection of really nice parts.
A case, which I'm not really that interested in personally as it's just a box and I don't look at a box, I look at the screen. this case holds a motherboard, a sound card, a graphics card, a hard drive, and I can pick the items that perform the best to my budget and to my personal needs. I can also get someone to make it for me and deliver it to my door in the configuration that I want and matches my needs perfectly.
I don't have a camera on my PC as I don't want one, I do have two monitors as I want two. I have more memory and a nicer graphics card than perhaps other machines, but it's basically made for me.
With Apple I cannot do that. I have to buy and put up with an item that someone else has chosen and decided what I want. But what if I don't want their choice, but I still like an Apple? I'm stuck.
I can pick up the phone tomorrow order my USB3 motherboard, my BluRay Drive, and by the weekend they are fitted and I'm using them. With a Mac, I have to wait a year and See if Apple seems those items worthy of fitting into their next offering.
I don't care how thin my case is, what metal it's made from or plastic, If the people in the shop have a badge which says genius on it.
To me this is all an act and a show for the general public.
The PC pushes the boundaries all the time as the individual components you fit into it can be the best you can get.
I would like Apple to do the same, why not fit a GTX580 into the top end iMac? Oh because we feel people don't need it, and anyway the case it too thin and we value the thickness of the case over the performance it could give.
It's just a whole different attitude. I look at my screen, I don't sit there looking side on at the thickness of the case wishing it was an inch thinner, and I'd happily accept my machine was worse to get that thin case.
For a mobile device, I can accept this is an important part of the functionality, but for a desktop?
I also accept for some people the looks and design of an item is more important than it's functionality. but not for me.
