There's an interesting interview with Charles Petzold up on the DotNetRocks site (audio stream: http://perseus.franklins.net//DotNetRocks_0077_Charles_Petzold.asx)
Charles covers a variety of topics, but especially interesting to me was his own struggles with book publishers (e.g., lack of promotion, Right of first refusal, etc...) Also interesting was Charles's comments on the glory days of PC Magazine with people like Jeff Prosise and Doug Boling. I was lucky enough to catch the end of that era. Plus, he's got some good insights on DOS TSRs, and why people were ready for Windows.
I feel old... :-)
