It doesn't make a whole lot of difference at the moment; at present the main utility is related to genealogy rather than health, which the current genotyping chips are adequate for. Until our ability to interpret whole genomes progresses beyond its current rudimentary level, there isn't much more for you to get excited about. In any case, you just have to wait a few more years and you'll be able to get (the non-junk bits of) your genome sequenced for close to $50 anyway.
