I have a 21 inch "tablet" hanging on my office wall, it's pretty useful as a dashboard and I can put it on a standing desk for typing up emails and watching videos, http://www8.hp.com/us/en/ads/aio-products/slate21-pro.html

would be nice if it wasn't power cord bound.

Not really, it's heavy, like ~14 pounds.

It's definitely useful though, a good niche product between desktop computer and tablet.
