If it’s ugly, it’s not Apple anymore.
On that note, the best iPad size is 9.7”, still has the perfect form factor for a tablet device, if you want to hold it close and use it everywhere, minus the “folio”. If I need a larger screen on a light portable device, I’d use a MacBook Air, not an iPad. Besides, I quite like iPad’s on-screen keyboard (writing this on an on-screen keyboard). I could never grow on the separate keyboard.
