"That screen alone, however, is worth the upgrade - it is the best phone screen Samsung has ever produced, and addresses all weak points of Super AMOLED displays so far in one fell swoop.
The 24% increase in battery size alone is worth the upgrade, too, as it brings top-notch endurance to the handset, and the juicer is on top of that replaceable.
Or, if you are buying a Note for the fact that it sports a stylus silo, you’d be happy to hear that the S Pen is much improved now - easier to handle, with a more natural ink flow, and a number of handy new features like Air View and Pop Up Note.
These three in aggregate make the Note II worth it both for those that are upgrading from the original, and for first time buyers. When we throw in the very good pictures and video capture, the excellent loudspeaker, the good call quality, and the expandable memory"

Ich warte noch die Tests und den Preis vom One X+ ab, aber das klingt alles sehr, sehr gut.
