One of my goals this summer beside looking into Pinterest and alternative sites to use besides Google Apps for Education is to try out Evernote. I have it on my iPhone and have clipped a few items, but I am just not comfortable with it yet. If you are unsure of what Evernote is, watch this video.
With all of the 1:1 or tablet programs out there these days, Evernote is a great tool for students. See what an actual student has to say in this video.
There are a TON of great tutorial videos on YouTube. Give it a try this summer.
