Single hand usage of phones
Few months ago I've posted here (http://www.theverge.com/2012/5/14/3019165/3-5-inches-not-so-fast) that one should create an entire new OS that enables single hand usage, since more and more Yao Ming phones are enjoying popularity right now.
I can't help but notice that in the latest and biggest phone, Galaxy Note II, and an upcoming phone, Asus Padfone 2, both uses a virtual button on the left side of the screen, very similar to the diagram I've posted in my above mentioned post. The virtual buttons in those two phones are almost system wide, meaning it is there in almost all the apps (except that for Padfone 2 it is not appearing on the home screen)
I am looking forward if someone creates a real OS that allows single finger control.
