Evernote

I just started using Evernote, and it’s amazing. The automatic OCR is a killer feature. It also has so many different interfaces: desktop, web, generic mobile, iPhone, and even IMAP; it’s amazing. The ability to email notes into notebooks, maintain multiple notebooks, save searches, and publicly publish notebooks - all combined, it’s an amazing system that is remarkably easy to use, considering the depth of its powerful features.
