I've made the decision to give up app development and go back to plain old webapps. Google's requirement to update the "targetsdk" for every app appears to be a "war on free", as only people making money off their apps are willing to jump through such hoops. I expect the noose to tighten even more as more app developers comply. So rather than fight it, I decided to throw in the towel early. I expect Google will try to walk a fine line of getting the right number of developers to jump ship, but I'd expect to see a lot more hobbiests switching back to web development in the coming years.
