1) Can be used while long cord plugged into 110/220v?
2) Battery can be charged without removing battery?
3) Produces .mpeg video files NOT .mov!
4) Better video at night time than the former DSC-P100
Extra 5) Has audio plug so I can use lapel wireless mic?
1) is easy, most digital cameras can use AC adapters
2) batteries need to be removed because they get hot while charging and need to be open to the air to protect them from overheating
3) you will have to do the research re: mpeg video. Call Sony for this. 800.222.SONY
4) Unless you spend the money on a real video camera, you will not get less noisy video no matter what P&S camera you buy
5) The use of external mics are limited to proper video cameras, usually ones that cast in excess of $3,000
