I was on the phone and wanted to make a note but wasn't sure of the quickest, best way to add a brief, note. Voice? What if you're in an area/situation where voice would not be appropriate? Thanks for any input.
I use Evernote.
With it, you can write notes, attach several types of media to a note, take a picture/snapshot, record audio/dictate. There's also a handy sync feature.
