I also use the notes feature that came with the phone. It is easy to pull up and I can dictate to it if I am home with wi-fi, or type into it if I am out. It syncs to my MacBook wirelessly (with no effort on my part), so sometimes if I need to make a note on my phone when I'm going somewhere (directions, shopping list etc), I will type it on my laptop, and it will instantly be on my phone as well.
The one issue I have with the notes is that on the laptop they are editable but as far as I've been able to tell, one the phone they can't be edited. So when I was at a Mother Earth News fair and trying to take notes on the workshops, if I made some notes and then a few minutes went by and the phone screen turned off, when I turned it back on again, I had to start a new note. So when I got home, I had 100 notes I had to amalgamate into one individual note per workshop.
I'd love to know more about EverNote - perhaps I wouldn't have that problem with it?
