I agree that the title of the note should default to the beginning of the note content. Especially since the most useful view (the List View) relies heavily on the Title of the note. I wrote a program here to retitle a batch of notes (instructions at the link). You still have to export the notes, run the retitler, then import them. But if you've taken a lot of notes on your phone or tablet, this is the best way to convert them. I'd really love to have Evernote make this program obsolete by providing the default note titles on devices, the same way it does on the desktop.
