Telekinesis! Another novel one that isn't time travel or flying!
I agree, this would be just a super cool thing to be able to do, that's reason enough to want to be able to do it! Although, yes, I could see that physical laziness would just be right around the corner! Also, the ability to negatively (and presumably without notice) affect situations in a form of "justice" would also be a ongoing temptation....
Oh your right would be hard some days to not make you boss spill his coffee on his shirt.
