Display and Speaker Quality
The 5.5-inch display on the Note II is large, but not too large that it ever feels too big to be a smartphone. This probably comes from using the Note previously, and owning multiple 4-inch (or thereabouts) smartphones. If you're coming from an iPhone (not the iPhone 5), moving from 3.5 inches to 5.5 inches is going to feel like you're holding a tablet in your hands.
While the display is big, that never automatically equals high-end or quality. Sure, 5.5 inches is great, but the 1280x720 resolution really brings it down. This comes into play when trying to multi-task with multiple windows on the Note II.
The 1080p display on the Xperia Z from Sony looked much sharper, so I suggest before you think about buying a Note II, see one in person. If I had to give the display a separate score, it would receive a 7/10 at best.
The external speaker on the Note II is great, something I expected from the not so average sized phone. I used the Note II to watch some videos, and play some music, both of which were great experiences on bigger than life smartphone.
