In my opinion, web apps and mobile apps are steps in the direction of Desktop Apps. In my view, the only practical way we will achieve both the convenience and security that users expect (and no one on the desktop delivers) is to package applications as Xen/Qemu-style images running distros in the spirit of Damn Small Linux where each VM is completely specialized to run (and keep updated) one and only one application. Every other implementation I've seen requires both too much security/administration expertise from my Mother and also, at the same time, too much expertise from the millions of random, BS developers around the world.
