I think this zoom might start sort of a new easy audio-video era. After all the zoom h4 has been one of the first pocket recorder, followed by a lot of others (often better).
The most interesting aspect -to me-of this product is that it seems that it has a special eye on audio, which is the great issue with camcorders now. It's rare to have a mic input on consumer camcorders, and never there is a line input.
Sure the audio quality of this zoom will be better than camcorders'; I'm curious to see wether this thing has an external line/mic input.
I think that having a good external mic preamp now might be the best choice to make, as there soon will be other new pieces of (video)recording gear which will need a good sound.
