My interest...
...is in the low power range. It's just like the photographic megapixels race, everyone wants more numbers when I want better quality at a lower pixel count.
What I want is a low power system that gives me a reasonably performing desktop, and despite the promise of ARM, nothing serious has yet been delivered in desktop form.
I played with an ITX format Sedatech, but it just isn't there yet. I also think that desktops which perform but use less power would be a big selling point in business as well; just think how much power would be saved by an organisation that chews half the power on the desktop.
