iAwriter is very good for typing text, the interface is perfect for that. I think it can be very useful for people who write a lot on their iThingie. I tried it for a while but uninstalled it because I don't have that much use for it, and because it seemed to react rather badly when it tries to synchronize and there is no Internet connection. This is a problem for me because I do much of my note taking on the underground train where there is no 3G.
I got an alert this morning that
JuneCloud Notefile is on sale. I am torn because I really love how the app looks, from the screen copies, but on the other hand I don't need another note app, I have too many already! From what I can see it is similar to SimpleNotes, but with a better looking UI. You can take and synch notes between iThingies, Mac or Windows PC, and there is a web app too (very important for me).
