In 2007, if you said you were going to download an app to edit a high definition movie on your smartphone you'd be institutionalized.
Why? I don't recall the first time I saw a phone that came with video editing software, but I'm pretty sure it was before 2007. So if someone had said "in a few years this software will be easier to use and can edit even higher resolution video than it can today", I would have replied, "well, that sounds obvious"
