I am not an organized person. My calendar was always on three different electronic devices that I never quite synced, my contacts were all over the place, and most of the notes I took were on scraps of of paper flying around my car. The nice folks at Apple took pity on me an came up with iCloud. It's incredibly easy to use and allows you to keep track of everything on all of your Apple products. I can also sign in on the office PC and get whatever I need. iCloud has a lot of capabilities that I'm just starting to discover, but the thing I really love is the simplicity.
