There is a fairly neat little software application called Evernote. You can copy all sorts of things into notes, save the notes. The notes are then accessible from any other computer you use once you sign in - Mac or Windows. Also, available off-line - although I haven't checked out that feature yet. I've been using it for a couple of days - it looks pretty great.
The software is free, at least at this point - they are in beta. They are in closed beta. Beta means it is still in the experimental stages. Closed means you need an invitation to use it. You can get an invitation by signing up for it and waiting for an invite. Or email me and I'll send you an invite.
