I got my G1 a couple of days ago, upgrading from a Wing.
So far I am not really impressed with the G1, so far:
1. Does not automatically show missed calls.
2. Taking photos is a pain, takes a long time after you press button to actually snap a picture.
3. Voice calling does not recognize anything.
4. No speed dial.
5. No MS applications (word,excel)
Am I missing something or are these serious draw backs?
