Access Notes Offline:
One of the premium features of evernote is "Access Notes Offline".
One of my friends says most of your notes are cached so you do not need to get a premium account for that.
In a test I searched for a common term in my notes. On my android tablet which I've had for a couple of years 75% of the notes were available offline (in airplane mode), while on my iPhone which was replaced about 4 months ago only 10% of the notes were available offline.
