I'm looking to get this phone around Christmas time and one really important thing to me (coming from a Palm Pre...LOL) is battery life. I really want my phone to double as an mp3 player so I don't have to carry the two separate objects around, so I'm interested in not only knowing how the Hero's battery life is normally (Fairly heavy texting use and a decent amount of browser usage), but with the function of an mp3 player added on top of that.
