Agree on the keyboard discussion... Tablets and iPads etc ... Have lots of keyboard... Which is covered in 2.1.1 Furthermore Detlev has a good start on the modified gesture issue 2.5.3 Modified Touch: When touch input behavior is modified by built-in assistive technology, all functionality of the content is still operable through touch gestures.
