I have been using Evernote for about a year and a half. It is one of my most used programs. I have the client application installed on both of my home computers and on my work computer. I have the app on my iPhone. This configuration allows me to access my data in Evernote from any computer or my phone. 

Following are some of the ways I store information in Evernote:

-Pictures of business cards

-Copies of receipts from online purchases

-Articles I want to read at a later date

-Clips from webpages for things I am considering buying

-Research Articles for a work related project

-Family information that I might need in case of an emergency

-Recipes

-Ideas I want to cover on my blog

There are many other uses of Evernote and Andrew Maxwell has posted 100 Things you can do with Evernote on his blog.
