I've been using EverNote 3 for about a month now and I'm really starting to like it a lot. For a while I had been trying to work out a ubiquitous way to capture and store digital documents. Articles, HowTos, Manuals, Bills and Statements. All of this stuff that is worth saving but needs to be in a searchable form.
EverNote can do this from a web browser, Outlook, desktop application or by emailing to a private address. You can also created Notes free form. Recently PDF importing was added to the Mac client and will make text inside of PDFs searchable. The search feature can even find words within pictures.
Right its and invite-only beta with a 200MB quota.
I've got 15 invitations I'd be happy share. Send an email to evernote.invites@mikehunsaker.net.
