This thing is still the size of a small photocopier/large desktop printer. And requires a swab from your mouth. And it looks as though it still takes about $100 in consumables. All sorts of chemistry still has to happen to get DNA out of cells, replicate it into a testable amount, then pattern it.
However, I've already read about the disposable chips full of nano-fingers which can use minute electrical charges to sort DNA, that is the core of the technology, and I bet this thing uses them.
If someone can figure out the solvents and chemicals that unbind the DNA from cells, and cut it into identifiable genes, and put those onto the chip, kind of like how Polaroid film had it's developer and fixer all built in, then you'll have the true portable DNA scanner that can just be run from a smartphone etc.
