"Great recorder, wants to be in your bag wherever you go"4.5 starson by JanWillemArnold
Pros: High quality recordings, very usable as a USB audio device also, works seemlessly together with Garageband and Audacity, mp3 encoding, easy interface, world adaptor
Cons: Bit bulky, configuration of Cubase LE in OSX is complicated, power hungry, battery life can be rather short
Summary: Overall weight with batteries is 350 grams. Playing around with it intensively it drained a pair of Duracell NiMH 2650 mAh in just a couple of hours. The side of the case even felt a bit warm. It is power hungry - not so strange if you take into account the things it does. Does it matter? Not really, just take a pair of extra batteries with you. (The Sony DCM50 seems to run longer on batteries but uses 4 instead of 2.)
It will take some time and playing around to learn how to use this tool in its best way. This is really a tool that you have to learn in order to get the best results. What is the best position for the microphones, narrow or wide angle etc. Since it can be used in a variety of situations it is good that it has so many options.
Clipping sounds nasty as always with digital devices but can be avoided easily by choosing a lower recording level. Dynamic range is such that it will always be considerably larger than the background noise in the place where do your recording. So simply make sure that your peaks do not go higher than minus 12 db.
The mains adaptor (switching type) eats everything between 100 - 240 VAC/ 47 - 63 Hz. (I bought my unit in Europe, such details might vary between countries). This makes the unit usuable all over the planet. It doesn't get hot. It has a single 5V output. I guess you'll be able to feed the device from another 5V power source without difficulties.
My three year old son was able to do basic operation within half an hour. (Play, stop, record...)
I love this device right now already and will use it for interviews, meetings, podcasts and audio registration at video recordings and in the theatre.
