That older phone's 5.3-in. display made one-handed use uncomfortable, but landing a thumb on the far corners of the Note II's screen verges on impossible. You need to roll the phone slightly in your hand just to get the other side of that AMOLED screen close enough. Taking pictures one-handed may be even more awkward.
So if you will use this thing, you'll need both hands free. If you accept that requirement, what do you get in return?
Reading and viewing are certainly more pleasant on that larger expanse of glass; with its 1,280 by 720 pixel resolution, you can fairly describe the Note II as an HDTV in your pocket. That extra space also allows you to play videos and view Web pages in small pop-up windows.
Like the original Note, this model includes an S-Pen stylus that you can extract from a well on the side of the phone. It can function as a more precise substitute for a fingertip; if you depress a tiny button on its side, the S-Pen can also bring up shortcut menus and clip selections of the screen as screen captures.
