Book excerpt: In this eagerly-awaited new book from the author of the best-selling Nostalgia Nerd's Retro Tech, Peter Leigh takes a fun, informative and irreverent romp through the history of more than forty pieces of personal tech, charting the successes, failures and oddities from over five decades of our obsession with gadgetry. From the Teasmade to the TomTom, mankind has been on a constant hunt for gimmicks that make life easier, faster and more entertaining, and as yesterday's 'must-haves' become today's museum pieces, there's no better time to take a nostalgic trip through tech's back catalogue.
