Ya the MinIon is more of a DNA sensor than a sequencer in its current incarnation, but awesome for portability. Super expensive per base though. If they can't improve the cost significantly along with the accuracy it will never be a competitive sequencer.

You're wrong about the PacBio though, the raw reads are random and cancel out easily with consensus. PacBio is the least biased and therefore the most consensus accurate next-gen sequencer available. See my other comments for some citations.
