Meet the 'Phablet' - Samsung's new 5.4-inch Galaxy Note smartphone/tablet

Samsung's brought back the PDA or at least innovated the thin space between large smartphones and tablets. Revealed recently at IFA (Internationale Funkausstellung Berlin), the stylus toting smartphone features an HD AMOLED screen that's not too different from the Retina Display but with a form factor, size and notepad capability that's sure not to attract any patent lawsuits. Is there a place in the world for a 5.4 inch smartphone?
