I’m a big fan of using Evernote (http://evernote.com/). I use it to record notes, photos, audio notes, and clippings from web sites. I have some overseas colleagues that use even more than I do. You can sort noted into groups (notebooks) that relate to a topic or project.
When you search the Internet, you can have google search your Evenote database for notes that you have previously written or saved.
This movie shows you how to create a note, and add audio or photos to it. It also shows you has to create a new notebook to collect all the same notes together, as well as showing how to use the web clipping plug-in. Then it shows how to use syncronise the notes from your mobile device to your desktop, and back.
