The iPod touch lacks the Notes application that is on the iPhone. As a work around for this (until Apple gets the message and adds it via a software update!) you can create a Contact called Notes and use the Note field of the contact to record snippets, to-dos, etc. on the go. The Contacts app on the iPod touch only shows fields with data in them. So Set the first name filed to Notes and put text in the Notes field and these are the only two fields that will be visible for that entry. When the iPod touch is synced with MacOS X the Notes entry and its associated text will be available in AddressBook. And vice versa, changed in AddressBook will sync to the touch.
