Evernote vs DEVONthink and GTD

One of the things that attracted me to computers is their ability to remember large amounts of information and retrieve it quickly. I was an early adopter of electronic organizers, back when the state of the art was a Psion Organiser. I later upgraded to a Casio Digital Diary, then eventually to various Palm Pilot devices, an Apple Newton, and so on. The PDA craze brought in desktop sync, and for the first time I could prepare entire databases of information and put them on my device for easy access.
