I agree that the choice of movies is questionable - after all, I only need to log onto Hulu to watch the full Ghostbusters movie (and its sequel, and dozens of others). True, I have to watch ads, but its a small price to play.
Also, I doubt the USB movie will be a Blu-ray killer. As the article mentions, the display quality is unknown as of yet. Even so, judging by the number of software manufacturers that have opted to use a dongle to secure their licensing, I'm going to guess that the movie dongle license system will be equally lack-luster in its appeal.
