Sounds like a great idea.
I do use the stylus alot, especially when my nails get worn out navigating those tight spots
I hear that capacitive screens use a glass surface which >
a) adds weight
b) are crackable
I saw an iPhone with a shattered screen a few months back. It looked like a shattered window with the glass left in place.
Maybe HTC will use a lighter weight, shatter resistant material since the existing screens probably won't be able to be used with their new capacitive screens.
