I got an Evernote invitation from a friend and in my limited usage, this service seems promising, especially to people like me - information addict :)

Evernote works using web, mobile phone, and as desktop application. Now, I can access my valuable notes seamlessly and centrally.

Evernote is in close invite only beta. You need someone to invite you or you can request for invitation thru their website. I still have some invitations available left with me, anyone interested, just comment here or contact me, and I’ll send you one.

Update: Interesting review of Evernote in TUAW.
