What are people using on mobile for easy notetaking?
On iOS, I use Drafts because it opens to a text field and doesn't make you think about where you want to put the note before you write it. Its interface feels like it would be a bit overwhelming for the average person though.
I also still don't have anything that syncs between multiple operating systems. Long ago I used an app called Droptext which presented a list of text files in my Dropbox, and that was about as close to sync as I've ever gotten.
