I'm getting ready to teach an undergrad course (juniors and seniors) on "History of Computers and the Internet" for the first time in 7 years.

I'm looking for suggestions on three things:

1) A recent book on the history of personal computers that's well-written and exciting for undergrads. I used to use Fire in the Valley, but that's very dated now. 

2) On history of the Internet, I've been using Janet Abbate's Inventing the Internet for years. It's a great book but somewhat inaccessible for undergrads, and now a bit dated.

3) Books or articles -- again, exciting for undergrads -- on history of the WWW. Please, not Tim Berners-Lee's awesomely self-centered memoir.

Thanks for any and all.
