Thanks for yor answers. Yes, it will be the primary use, let's say 95% of the time. Also the USB mass storage thing is very attractive.. I don't really know, I think it'll be from an analogue source, not a microphone. But the 600D doesn't have neither analog nor digital, anyway, so it shouldn't really matter... If the audio quality of the HiMD is far superior, I think I'll go with that...
