Someone can summary the content ?
I did listen to it.
They see themselves as repository for all your textual info (web clippings, text from pictures, hand written stuff). The move to the web is to allow for easier access to this info. Free and subscription based services are planned. Nothing special here. Zoho and others already provide similar things.
IMO, the really interesting part however is that this info would be accessible using an API. This opens the door to other programs using this info.
As an example, you take a picture of a business card with your phone and send it to evernote (you get a special email address to contribute stuff). Evernote does the OCR. Other programs, such as my own SQLNotes, can use the Evernote API to retrieve this info to create a new contact.
Combine this with the Microsoft Sync Framework and you could sync this business card with a whole slew of programs (Outlook, Google, Hotmail, etc)
API should be out in a couple weeks (read a couple of months...)
