Default [Q] is Google Glass a game changer in the post PC/Mobile revolution?

I have been chasing screen size since O2 flame, htc hd2, dell streak 5, note 1 2 and now 3. With GG, and if it does all the video and web browsing i will start the reversal that is finding the most powerful phone that is the tiniest.

Although it is in its early stage, I am hoping that the GG can display exactly what I galaxy note 3 display and once tethered to the phone, the phone can become the mouse for touch UI. That is GG can act like a monitor plus added features uniquely built for it but also the resolution needs to increase as well, 720P is good enough for me.

What do you think? is it possible?
