I just picked one of these up for my wife last week as an anniversary present. I have not had much time to play around with it nor has she, but it seems incredible what what we did with it.
We bought the HFS 10 because I wanted the internal memory plus the extra card. It is amazing how compact the unit is and how light weight it is. It is going to take some time to get use to, we have had a Sony unit for years, so we know those controls in our sleep. I need to crack open that "War & Peace" size book and start reading, our vacation is coming up at the end of the month.
