Never had any use for things like the iWork or Office suite. I never really liked the concept of a tool that can do a lot of things but every single of those very badly and inefficiently. PowerPoint may be the only program that actually has a use (although I don't really need it for work). Word documents just look laughably bad, Excel is of no use at all and I never bothered to use the rest. And iWork is even less usable in my experience.
