Should Microsoft Make Huge big display / screen?

Windows 8 looks great even on large display. Microsoft produces lots of input device … mouse, keyboard.

I feel they should be producing and get involve in display technology too. With Windows 8, they can produce a dumb glass …. with great display and wireless connection. So that all Windows 8 tablet, laptop … or phone can wirelessly ‘dock’ and use it as for some relax consumption of video and metro app.

Should MSFT produce cheap dumb ‘glass’ which can pair with their Smart ‘Glass’?
