This is avery nice combination:
Download PlainText for your iPod/Ipad and synchronize your notes with your own Dropbox folder (within a dedicated folder named "PlainText" created by the plainText app)
Then on you Computer you can Write in a clutter-free environment with FocusWriter. Make sure that you save your work in the plain text folder in you dropbox folder and you have your writings with you wherever you are (mobile or not)
Here is a screenshot of my super-clean set-up (theme) in FocusWriter.
