Too much of this and we will see apps that are based on the lowest common denominator of all platforms. Developers will get lazy and you will get iOS apps that don't do anything when you rotate the screen, have tiny icons/graphics. Desktop apps with no keyboard shortcuts (wait...isn't that Adobe Air already?), menus, hover events, the list goes on. A neat tech demo, but in reality hardly anything developed in this manner is going to be able to compete with anything native on the platform, and the resulting time saved will be revenue wasted.
