Here's a website I'm using to send French Vocab videos home to parents. It's pretty much like Youtube for teachers since it doesn't have ads or inappropriate videos that pop up on the side. I haven't had too many problems with it, though there was one time when I couldn't get the video to display even though the audio was fine.
In addition to helping students take notes, the Echo Pen represents a new way for teachers to assess students while they're presenting or explaining something. You can even go back later to hear their presentations. I'd stick it under the Augmentation category of SAMR since improves one's ability to take detailed notes but doesn't bring you to a whole new level of assessment.
Google Glass is a hands-free video camera, translator, list displayer, map, clock, and much more all rolled into something you can wear like glasses. You can even share pictures and video taken through Google glass with others. I don't know if any educational applications have been advertised by Google yet but I can see how it could make lessons and assessment much easier (provided it all works properly).
