This definitely looks more like a phone. While the F3 is small, it's boxy design doesn't translate to pocket storage that well either IMO. I believe you could use a 1/8 > dual 1/4 cable to go directly out of a batt box and into the F4 combo jacks, that could definitely work. Good point. It's a bit cheaper than the F3 and the 4 AA's could negate the need for external power. I do think 32fp makes so much sense in the stealth world.
I actually think this is cool from the perspective of a musician/creative and dare I say it, content creator. It's obviously targeting that audience and I just think it's so cool someone could record, edit and distribute professional grade music from a little pocket device. I think I saw the lack of protruding external mics and got excited for a sec; a cheap, compact, 32fp 4 channel recorder is definitely something I would put to use. Especially one that sounds as good as the F3.
Those plastic faders on the front are a trip; they look cool but just scream "broken within a month" to me.
I will likely pickup a F6 at it's new price.
