The weird thing about this is that to make it bigger you drag the corner, which would be hard to accurately "click" with your finger. Also, if it's to be used widescreen, it takes up almost all of the screen, much more than the iPhone's keyboard (although similar to the widescreen keyboard on the iPhone).

To me, it seems more like they are just doing what they should do and making it resizable like everything else, and putting it in a more findable place.
