The only thing that I really didn't agree with was the slide about Adium. Adium is a great chat client that looks nice, is customizable, and supports more chat services than what Messages can. For instance, I sometimes IRC and MSN Messenger with Adium, and MSN Messenger is used frequently for communicating with some of my family. Also, while Dropbox may have some more competition now, they've also had more competition from Google with Google Drive, and it doesn't seem to have affected them too much.
