Apple Needs New Typography in iOS

I am still on the iPhone 4 and can upgrade to the iPhone 5 anytime. I thought about getting a Nexus 4, but now I'll just wait for the X Phone or the 5S. One of the things android is getting so right is the fonts! Roboto is the best font! I love it and have been using it on all of my English papers. When I look at my iPhone and iPad the font is so ugly! Apple should get rid of the default font - Avenir. Apple needs to create a new font for a better look. Does anyone like the Apple font over Android?!?!
