My newest thing is Evernote. Basically it's an online way to store lots of information, like to do lists, websites, pictures, etc. And it organizes everything for you. I don't know that I would find it useful in my classroom, but I would find it useful personally. I put it on my phone, and I'd probably use it when I'm at a store to take a picture of something I want to buy in the future (I do this all the time at the book store, then go home and buy it off of amazon used for really cheap, or put it on my kindle). Maybe I could use it to list ingredients, then check off the items when I'm at the grocery store. I don't see myself using it all the time, but I can see some useful times.
I couldn't really figure out how to right click on some text and add it to my notes. I got a message saying one note added, but it never appeared. Maybe it takes a while to process.
It also took me forever to figure out how to tag something. Even the help directions were for the old version, and I was using the new version. When I finally figured it out, I realized it was really easy all along.
