Sony's been throwing a PS3 fest here in New York and Richard Blakeley, gave us a first hand look at the PS3's web browser interface. Typing URLs with the controller is somewhat clunky as you can see from the video itself (luckily you can plug in a USB keyboard), but otherwise it'll let you open up to 6 different browser windows simultaneously and then tile them (Expose style) so you can see them all at once.
