Evernote looks interesting: it’s an information organiser for PC and Mac with some clever features including web clipping and the ability to email photos to it from your mobile phone. It then scans the pics and runs character recognition on ’em. It can also store audio and video, and seems happy with Office files and PDFs.
It’s in beta (by invitation only) just now, but if you want a go I’ve got a bunch of invites kicking around. Just ask for one in the comments.
