I read it too in highschool. I even found a Dover Art book containing a copy of that suited-frog spot art sketch he used and cribbed it for my blog. Wonder what old Cringely is up to these days
For a while he did a series of columns exposing the decline and mismanagement at IBM; he eventually turned these into an ebook that I purchased and thought was a reasonably interesting read.
More recently he had cataract surgery and had to move to a new home after his old one was damaged in the California wildfires.
