I've been meaning to recommend Evernote - a (mostly) free online notebook that has a few mind-blowing features worth recommending.
First, it has a feature-rich editor that let's you create anything from simple text notes to professional-looking documents.
Next, you can sync your notes on the web - and access them anywhere, from any PC, Mac, and/or iPhone. (Client freeware is available for any platform).
Now here's the great part: Evernote has incredible character recognition capability. When you search your documents, it will even find text in most images - with startling accuracy. (See the example above - where a search on the word "Amazing" finds it - amazingly - in a 1960's comic book cover image).
Evernote is free, but there is a limit to how much you can keep in your online account. I'm not exactly sure what the capacity is - but it's generous, and the limit is only on a per-month basis. Not a bad deal at all.
