I've tried to use it so many times, but I just can't work it into my own productivity cycle consistently. I end up using it for a few days, and then slowly forget about it. I know a few people with a similar story, but nobody who has actually settled on it successfully.
That said, I did pay for it for the year hoping that it would encourage me to use it (better organizing my work-life seems like a problem worth solving) - it just didn't...
I use evernote everyday. I put everything in there -- status reports I update every week, my own git cheatsheet, business ideas, documents I use repeatedly (e.g. instructions to ramp up new developers on my project), etc..
But what really got me using evernote is the combination of Fuji Scansnap + Evernote. Now any important mail or receipts I need archived I just scan them and they're in evernote forever.
And their iPhone app is a life saver, anything I need on the go, I retrieve from evernote. Forgot my health card? No worries it's scanned and available on my phone via evernote.
I love the product, but yeah it still boggles me why they need so much money and how you can build a big company from such an inexpensive product.
Evernote's killer feature for me is they do OCR of pictures you upload. I love it for snapping pictures of business cards, whiteboard drawings, notepads and sticky notes. You can go search for a word or phrase later and get a picture of your hand written meeting notes with the search term highlighted.
Their 60mb/mo free offering is much more capacity than I actually use though, so I've never needed to upgrade. But I totally would if my needs increased or if they had to lower their free tier allowance to stay viable.
