1. Stellarium -- don't care. Not helpful at all in my daily line of work. In fact, it's not even work-related!
2. Some, but few good suggestions here, but there seem to be many (better) alternatives to many of the apps listed here, free or licensed otherwise. I prefer Parallels Desktop 7 (you don't mention any or many Mac apps at all! CCleaner is for both systems now.
What a waste of time.
