Sparkle is great but, for some reason, it never works on the apps that I have that use it. I check the box to automatically update apps in the future and I still get prompted every time there's an update. Even then, I hit the update button and the update fails and then I have to restart the app, try again, and then it succeeds... until the next time there's an update and the process starts all over again. At least with the App Store, all my apps update at night and they're ready to go when I need to use them.
