In Japan, people still use feature phones. But despite the smartphone revolution, dumb phone innovation is not dead. Not when a phone can magically, (Transformer-ly) convert from a heart shape into something approaching a chubby handset you can actually talk into. Imaginatively titled "Heart", it'll come to Nihon in both red and black options, and according to our Japan team, weighs a mere 54 grams. Curiously, it doesn't launch until after Valentines' Day (late March), but when it does arrive, the phone will also come with in a special Sailor Moon iteration, with magical wand dangly accessory and livery.
