What a moronic concept for an article. It's like a roundup of cameras with square shutter buttons. A touchscreen interface is not a defining category of a camera, such as compact or SLR. When thinking about buying a camera, one does not narrow the field down to touchscreen only and then begin choosing.
Personally I loathe touchscreen cameras. It's a poorly conceived idea, designed by marketing departments to dazzle the unwary. The orientation of the screen - vertical with your hand at one side - means that pressing the screen moves the whole camera and changes your shot. Touchscreen interfaces only work properly when you can have your other hand behind the screen to support the device and provide counterweight to the screen presses (like on a phone).
