Unlike touch, keyboards are inherently targeted. While touch is
powerful specifically because of your ability to directly
manipulate the software you’re using, keyboards must first be
pointed at a place that needs text. They need focus. And here’s
where the iPad falls down.
It has no concept of focus. Or rather, it obviously does, but its
designers are in denial about it. Keyboard focus is littered
throughout the platform, from the presence of a cursor when
inputting text, to the software keyboard auto-hiding when no text
field is in use. When you’re producing text, this generally works
But the keyboard is used for far more than typing. Whether it’s
command-tabbing between applications or using shortcuts within
them, the keyboard is a critical control device. And it just does
not work right on the iPad.
Off the top of my head, I think command-tab switching should include the individual apps in split screen mode.
