Alas the information presented is an over simplification of the process. To actually sequence DNA with this USB thingy you need to prepare a so called sequencing library - and for that you need a fairly well equipped lab - expensive reagents and years of practice and skill ... a mid level biology Ph.D can prepare these ... in addition the flowcell sold by Oxford Nanopore often malfunctions and the whole run is a bust ... (behaves like this since 2014 ... so no, the technology does not seem to improve a whole lot)
