That would obviously more expensive than the $100 sequencing a lot of people are looking for, but for very privacy conscious people this could be available right now with a MinION[0] that's already in the $1000-2000 range, if you really want to take the whole device with you.
Wow, that's better than I expected! So maybe a resale market could develop on Craigslist or whatever. Buy one, get your data, clean and wipe it thoroughly, and then resell it. Maybe the refurbished price would stabilize at $500 or whatever.
I wonder how fast the flow cell price will drop. But even at $1000 I might be tempted, except that I'm so damn old, and never (as far as I know) had any kids.
While it mostly comes out to the same, I doubt the price will drop much, but rather they will release a newer iteration of flow cells with slower degradation or more redundancy.
There also doesn't seem to be any significant competition, as Oxford Nanopore has a very broad patent portfolio surrounding their tech.
So a customer walks in, provides a sample, and walks out with data on a thumb drive. And perhaps also with the module that was used for the analysis.
