At Eye on DNA, Hsien-Hsien Lei points readers to Ann Turner's comparison of 23andMe and DecodeMe. As a customer of both services, she's had a good look at both and offers up comments on their coverage (don't base your decision on mtDNA or Y features unless you're interested in what she calls "deep ancestry") as well as graphical user interfaces, genome browsing features, and medical aspects. Despite the probability of less expensive tests becoming available soon, "if you decide to proceed, I don't think you can go wrong with either company," she writes.
