Vincent, I sort of felt the Photobooth app being useless as well and Steve has only shown it to brag about the ingenuity of his designers comming up with using the LCD backlight as a flash. But the tiny app becomes real useful as soon as it’s integrated into the system. And I’m sure it will. Setting up your IM avatar (that’s also used in the system login, much like Ubunutu’s About Me) would simply link to launch this little toy. And suddenly it’s not so useless.
