I'd like to take a moment to focus on that last point: Chrome has become the memory hog that caused us all to leave firefox but for the much more egregious reason of trying to be something it's not.

Now when I close chrome it wants to stay open like an over eager registry cleaner that hopes to hide behind the always on functionality and thus obscure that fact that it's done nothing, only Chrome's reason is the slightly more nefarious "we'll keep you informed while tracking all your desktop mouse movement" it also has the unintended consequence of making it difficult to restart the browser in cases of memory leaks.
