I think there should be a easy way to access our notes on any device.

It will be really cool to have new app called Yahoo Notebook! A dedicated place for us to store some notes which will be auto-synced with our accounts, so no matter what we use (the web browser from Desktop, or the new Yahoo Notebook app from our mobile phones)

Another interesting feature to have in this new Yahoo Notebook app is the option to SHARE. So if anyone wants to share some note with some friend that can be done via the SHARE button from inside the app and she/he can easily share any notes via Yahoo Mail!

So basically this share button will open the Yahoo Mail app and the NOTE that we want to share should be already there in a new draft mail. All we need to do now is to write the email address of our friend and send it.
