The Joy of Evernote

One of the most useful tools I've come across is Evernote.  It's a program that allows you to write, copy, and store nearly anything you want: text, pictures, audio, video, web pages, etc.  There are downloadable Windows and Mac programs, a web interface, and iOS and Android apps as well.  They all sync with each other, so you can have your notes available no matter what device you are using.  There is a Web Clipper that you can use to copy the contents or URL of a web page you are visiting.  You can share notebooks with other users if you like.  It is remarkably easy to use and free if you don't upload too much per month.  Premium plans start at $5 per month.  Try it out at www.evernote.com.
