"Remember the thing we sold you before? Well, it wasn't that great. But now it is. Give us more money?"
Who does not want DNA 2020? I do. [NOT in this case]
All in all, probably not hugely worth the expense. But I guess the novelty of it was fun.
Yeah, for me it was half novelty and half trying to figure out more about my father's side of the family. My father died just before I turned 13, when his father died about a decade ago I asked my great uncle what he knew about the family... he didn't even know his mother's maiden name which I only discovered at the end of last year, several years after my great uncle also died. I can trace part of my mother's side back with confidence to at least the 17th century, my father's family had gone cold in the early 1900s until I discovered my grandmother's maiden name.
Novelty is also why I want my whole genome done. Once it's down to a few hundred dollars I want to have it done and ultimately have it printed and put in binders, purely for the novelty.
As a 23andMe customer from a couple years ago, it never even occured to me to try re-running the results.
