I’ve just finished reading Steve Wozniak’s book and I can tell you that it was really an interesting experience. You’ll only be able to enjoy it if you’re into the history of the PC. In about 300 pages you’ll learn about his early inventions (his school calculator project was really interesting) and on how he developed the Apple I/II which ended up conquering the market.
The only thing I didn’t like is seeing the same thing repeated several times (not sure why, but it seems like American books of this gender tend to repeat the ideas contained on it several times, which makes it a little boring). Overall, I’m giving it 7/10
