You can't gaffer-tape a Schoeps ORTF rig to a windmill (which I did with my Zoom).
You can't easily take a rig into a 1.66-mile underground abandoned train tunnel and record without getting water on your mics (which I did with my Zoom).
You can't set up your rig on an airplane to get captain announces or the seatbelt sign or the take-off and landing without the stewardess seeing you and telling you to turn off your electrical device (which I did with my Zoom).
You can't walk around with 10 Gs worth of mics and recorders and record ambiences in Mexico, Russia, Columbia, Venezuela, Africa, etc. without getting robbed (but I did with a Zoom!)
You can't do lots of stuff that you can with a Zoom which makes it absolutely fantastic as a recorder. I have used many recordings I've gotten off it in my projects. I'm not saying I prefer it over a nice MK5 pair or a Neumann 191, but in certain instances I think it's a perfectly capable recorder and can yield usable results.
I've also used my zoom to grab wild dialogue lines on set with a second unit and they worked well.
Who the %&#* cares where the recording got transferred into electrical signal and then converted into 0s and 1s? If it sounds good, it's good. Period.
