I discovered this a while back, but over the past couple of weeks I have had plenty of time to play with it. I LOVE IT!
It is just like one note, which I loved, but I could never get it to sync right and since I had the 2007 version I couldn't update it on the go. Evernote solves it all!
I have an android phone, an ipad, and a laptop. It has a version for each of my devices as well as a web based application and a desktop version for my PC. I can sync this anywhere. I can also share my notebooks with anyone I choose. They can edit the notebooks or be granted read only access (with Premium membership).
Most people will be just fine with the regular free account, but since I use it for work as well I find the file attachments feature (any type with premium, pdf's and photos are allowed with free) invaluable.
Want to find out about it watch a great video here:
I have already started a Christmas notebook so when I see something I can take a picture and add a note (directly from my phone) and there is no guessing or trying to remember. This is one of the best organizational tools that i have seen in a LONG time.
