My vision for these boards is not to display graphics, but to send/receive data from the internet and a local network. I'm not going to use a Pi to watch movies or some other resource-intensive task. I'd just as soon use the power of GPU that comes with Pi for some other task besides video.
What would be interesting is if one of these boards would be designed such that, by pure coincidence, it could fit into an Apple form factor (cheap/old/maybe used). I've read that in, e.g., Vietnam, people with soldering irons do all sorts of hackish things to iPhones.
Or maybe a market for curved edge form factor casings develops. Maybe it already exists. But I never saw any Apple-like form factors in the mini-ITX offerings. Whenever you see something with a cool form factor, it seems it's always a proprietary package, hermetically sealed, not easy to tinker with.
