iPad One Hand Use With Air

I am having last minute thoughts about the Air vs. Mini. After looking at some photos I personally don't think there is a HUGE difference in screen size on the devices. But the Mini is smaller which make it better for one handed use or gaming. For those who have the Air, how is one handed use? Are you able to hold the device in your hand and at least reach the middle of the screen with your thumb in portrait mode? This is a simple to do on the Mini, but how is it on the Air?
