For note taking I use the open sourced Notational Velocity [1] (actually I use nvAlt [2] which is a fork that has some extra features like Markdown support). My two favorite features are that it can store your notes as plain text files in a folder of your choice, plus there's syncing through Dropbox or Simplenote. Notational Velocity is a Mac app, but with Simplenote you get x-platform support.

Yeah, I love Simplenote sooo much. The official app got a lot better when Automattic took over, so I use that on Android, but NV on Mac and ResophNotes on Win7 are excellent.

Not good for rich text and images and web clippings and such, just great plain text syncing.

I love simplenote too, replaced my notepad.exe.
