Re: "keyboard doubles as a capacitive multitouch trackpad"
It's a real physical keyboard, with proper shaped, physical keys that move just as they should when you press them. Just like BlackBerry are famed for.
It also a touch pad. And for a mobile device it's large. I'm assuming the screen is also touch enabled just like their other devices.
That's probably counts as being clever, or possibly cunning. It's also an improvement on the little track button that old blackberries used to have.
