This might be one of the most important historical pricing repositories that track tech trends ever produced when it's done. Imagine tracking the weekly per-MB prices of hard drives or even more volatile DRAM from 1979 to 2009. And then there's tracking the emergence and transition between technologies, correlation against production yield information, corporate histories...this could be a backbone all other North American computer history could be hung off of.
It's a time long gone, but 2009 wasn't that long ago, and reaching from the beginning of personal computing to then is an amazing thing.
