I find that my nose is only really good for scrolling. Having better accuracy for nose pointing would make it more useful, but I think I'll stick to using it au natural vs. this stylus.

I absolutely have scrolled my phone w/ my nose before. It was never necessary back when phones were a reasonable size to use one-handed. Now that every phone is a tablet-sized monstrosity I resort to nose-scrolling in the few-and-far-between times when I'm forced to use my phone one-handed.
