"Mozilla’s Head of User Experience Aza Raskin has just posted a video preview and extensive post covering the concept behind of one of Mozilla’s latest endeavors, Firefox Mobile... The GUI looks very cool, though raw... Firefox Mobile will be usable on touchscreen devices, keypad-operated devices and everything in between."

Cool little video. Although I'm convinced it'll work very well on mobile-sized devices. Mini-tablet-sized devices would work well though.
