I think going 16:9 with the iPhone 5 was fantastic. Long portrait for reading, Twitter, etc. and the perfect for viewing video content in landscape mode. Works great in a portable handheld device, but would it work with the iPad & mini? I think it would but it's maybe an awkward shape for a tablet. Would be good for movies, no over sized black bars top and bottom, plus I think gaming would benefit too. With thumbs/hands on screen for controls there would still be plenty of viewing area in the centre. What do ya reckon?
