Here are 17 of the ways I am using Evernote for. Interested to hear what else you are using for?
- my GTD lists
- saving interesting emails
- clipping interesting webpages
- clipping the sales confirmation page when I place an order online
- saving travel tickets/itinerary from airlines etc
- photographed all my old journals for 1) backup 2) searchable text
- import all scanned mail from Earth Class Mail and other sources so I can search and find stuff
- photographs of receipts
- import of all files in MyDocuments fold for search and backup
- keep track of important numbers and contacts
- keeping track of goals
- saving notes from online courses
- project notes
- list of delegated tasks
- drafts of newsletter and blog entries
- shopping lists (especially ones weeks in advance where I might think of new items at odd hours)
- packing lists for trips
PS I used the paid version to get more notes and features ($5/month) but there is a free version too. It works on PC, Mac, smart phones and on the web in case you are traveling without your device.
