I worked in this space for over a decade. It's so weird to me to see the workhorse sequencing hardware like the ABI 37x/37xx series, 454, and Illumina machines now as literal museum pieces.

Nice writeup, but missing 2 newer sequencers:

We need PC revolution for biology. Put a box on every table we can tinker with.
