I noticed that notes, like Calendars, get synced with a Gmail account on the iPod touch.
But where do they get synced to? Where can I access them online?
There's a difference between syncing with iTunes and over the air sync.
If you set up your Gmail account to use over the air sync then when you open up the Notes app (on the iPod), you should notice a back button on the top left that allows you to change which account you use for notes. If you choose your Gmail account and start creating notes, you will start seeing them appear in your Gmail account, under the "Notes" label. This sync happens automatically once you press the "done" button on each note (as long as you have an internet connection).
This has nothing to do with iTunes sync.
You will only see notes that you create under this account in Gmail. You will not see all of your old notes. For that, see this question.
It syncs the notes from the Notes application on your iOS device to the Notes using a special mailbox on the Mail Accounts you have enabled (eg. your Gmail account here). They should appear in the Notes section in Mail.app on your Mac or in a label called "Notes" on Gmail.
add notes to your email address ex : if your email is [email protected] just type [email protected] and send it then you can filter it in your inbox with label NOTES
[notes]
to[notes.app]
as (imo) there are just too many things called "Notes" that shouldn't all share one tag.
