I have learned so many neat new technologies that I am really excited to implement, but there are definitively some drawbacks.  There are lots of phone apps that are really neat and I would love to use in my class, but many of them run into the problem of first do all students have a phone and since I teach middle school that is not usually the case. I have also run into the case that some of these apps can only be found on a particular platform and not on another.  Also, teaching technology, we constantly run into glitches, like the district server is down for the class, or three of the class computers are running updates. These are all problems that can be overcome, but it does make it more difficult to implement at times.
