While the idea seems silly at first, after thinking about it, the concept makes sense: a curved keyboard may be better suited for those typing with just one hand. According to sources for PocketNow, the photo above is from a Microsoft Research presentation. Think of how you hold a phone; your hand is slightly curved which makes tapping on keys in the upper left hand corner quite difficult. This is a curved SIP with a joined button QWERTY keyboard. Do you think this is a good idea?
