YouTube. I would like to have the YouTube app link with my real YouTube account, so my tagged favorites will be synced for quick access. Maybe I'm just not finding the place to set it up. Either way, I think this will become more important when video recording finally lands.
AD2P support. I have media and phone in one device, with Bluetooth capabilities but I can't use my HT820 headphones to dual pair? I don't get it.
Document support. PDF viewing, google docs/open office docs edit, etc. Would love to be able to store/edit google docs offline.
Video conf camera. I hope that a future incarnation of an Android phone would have the ability to either swivel the camera, or give it multiple aperatures. Also, for retinal scanning phone security, having a lens on the front would keep me from looking like an idiot when I wanted to unlock the phone.
Oh yeh, copy from text messages. I can copy from almost any other application or place. Why can't I copy from my text messages?
I am sure I will have more later, but I've only had my Pocket Monkey® for just over a week so the "new car smell" is still a bit overwhelming. For the money, this is by far the coolest piece of technology I have ever owned and am looking forward to future generations. I don't mind being a Guinea pig with the G1, I've been drinking the Google flavored Kool-Aid for years.
