I hated that 10 minute Disney video. The Playing with Media page was much easier to understand. I can't believe the attribution tools that are available today! I was in school with internet and everything, but geez, it has advanced sooo much that it makes me feel like it is a double edged sword- great and useful but encouraging laziness.
I think that Dropbox will be wonderful to use in the classroom this next year. Last year, I did a Lewis & Clark project and gave suggested websites for students to view and play on, but every class period, it was, "MISS!!! This website is NOT working!" (After double-checking their spelling, they'd eventually get it!) It will also be useful for students to access everything from home as well.
