It's interesting to note that Gizmodo is already taking this demo as a sign that the post-PC world is truly upon us. The statement is premature to be sure, but to fully dismiss the phenomenon off-hand is equally as absurd. In fact, it's probably worse. The iMovie app for iPad is $5 and it offers enough video editing firepower for almost all users. Vimeo's new app has an almost-equally robust set of video editing features and that's totally free. A truly serious (not to be confused with professional) photo editing suite can't be far behind.
