I have Skype, but because the sound is sometimes off with the mouth, I usually make more use of its "closed captioning feature" (e.g. I go "what?" and the person types to me what they said ).
I have Skype installed in my HTC EVO after it finally included video chat for Android!! It works okay cuz video not clear. Guess I was in dusk room. Will try bright room or outside on beautiful day. I don't use it much unless if my brother want to reach me through Skype.
