It doesn't answer all of your gripes, but I've gotten tons of mileage out of my Galaxy Note 3 and Papyrus. Yeah, it organizes things into notes and notebooks, but I usually ignore that and just email myself the notes I've just taken as a PDF for later review...and that seems to work pretty well for most cases...and I get to integrate those notes into the rest of my on-computer organization scheme.
