25 years of laptops and we still have these damn screens on them that are physically attached to the computer.

Any laptop engineers out there: I want a screen that I can detach from the laptop, velcro it to a wall or to a stand and let me use my laptop with good posture.

Buy a Surface Pro 3 and use a wireless keyboard/mouse. That's more or less what you're asking for. I will admit you'd need pretty heavy duty velcro to attach it to the wall, but it likely is do-able if you don't mind having a completely fuzzy-backed SP3.

There are many hybrids with detachable keyboards; they're not that far from what you seem to want.
