Coming from windows, I'd never had so much trouble with a compression format. "There is an update, do you want to download it?" *clicks no* The app restarts and says it all the sudden doesn't work... gee, I had no choice but to update. All for what? DMG is built in to Mac OS. So is tgz. Stuffit is an unnecessary evil. I've always disliked it, and now there's no reason to like it other than sentiment.
