1. Meeting notes. Evernote's the main repository for all my meeting notes. The tag function is an excellent way of cutting through piles of other notes to get context for meetings.

2. Receipts. I keep PDF-ed copies of receipts I make with JotNot Pro. Makes it handy to reference for claims and purchases

3. My son growing up. This is the best part of Evernote, IMO. I'm getting my little 2 year-old to talk into my phone with Evernote's voice note up, so I'm recording him as he's learning to speak and snapping photos of him as he grows up.

I've often called Evernote my external brain, but it's becoming like an external heart too :)
