dna sequencing - What good is the MinION?

This year, Oxford Nanopore MinION has been shipped to some researchers for testing.

The advantage of a table-top sequencer for diagnostics and personalized medicine is obvious. Similarly, research "in the field" and forensic science could be aided greatly by this device. My question is about the applications in the research lab.

What does MinION do that a well-equipped lab with access to Sanger and next-gen sequencing cannot already do?

How well does the MinION work? How powerful is it?

What important scientific discoveries are being made using the MinION?

While the website of Oxford Nanopore has a list of publications, the most recent one is from 2013. This is before the early access program began - I am particularly interested in developments since February 2014.
