20 Macs for 2020 was a fun series and, overall, I agree with the ranking.

Strictly for nostalgic reasons, I would have included the PowerBook G3. This was the first Mac I ever bought and I spent a lot of time with it in the first few years of grad school.

I ran the public beta of Mac OS X which was both incredibly slow and amazingly interesting. My recollection is that I only used AppleWorks and Audion. But, it led to a long interest in and use of open source software like R and LaTeX that continues to this day.
