Be VERY careful with using evernote on multiple devices. ALWAYS sync BEFORE editing. Evernote does not care whether your data is current or not, it will overwrite it one way or another. I wrote a whole whack of notes on my French course, in French, laboriously, and it lost a very large amount of them.
This does not happen every time. Usually it will show you both versions of the documents if there was a conflict.
So, be careful, evernote loses data.
