As the article says, in OSX Lion there is apparently a way to reboot your machine into "browser only" mode. Could be useful in a couple of situations.
A) If you are going to leave your computer unattended, maybe at home, and you want to allow people to check their email.
B) Kiosk mode. Maybe a computer sitting in a public area?
I don't think they are going for a play against ChromeOS here as the article sort of implies. Either way, interesting.
