i've got my eris, it's super slow, i hate it etc and i want the incredible. however, i just saw a video of a rooted eris and it seemed so much faster than my stock guy is. if i were to root it, does that get rid of the keyboard text lag? because this thing is awful and lags horribly when typing. question is: should i root my phone, or go for the incredible? would rooting my phone make me NOT want an incredible anymore? any ideas?
