For the last few years I've been collecting computer history books that I get at used book stores. Unfortunately, I have more just collected than read them, but I did read and enjoy Steve Jobs and the NeXT Big Thing and Gates: How Microsoft's Mogul...
Steve Jobs & the Next Big is a great read with tons of context about the tech world at the end of the 80’s/beginning of the 90s. Also, a candid view on Jobs’ reality distortion field.
