It probably won't have you clutching your sides and gasping for breath, but may bring a smile to your face.

I don't need any excuse to leap into the nearestsecond-hand bookshop when I'm out and about, but if I were forced to provide one, it would be this. You occasionally come across some real gems.

My latest find is “Computers: they drive us crazy!”, by Helen Exley and Bill Stott. Having been published in 2007, this now officially counts as an ancient document. You can try purchasing a new copy from Amazon, if you're prepared to wait until the book is in stock, which could be never. Alternatively, you could pay anything from a penny to almost £800 to receive it very soon if your idea of deferred gratification is having to wait for the tea to brew.

Because of the difficulty of acquiring this book I thought more than twice about writing a review of it. So regard this as an exhortation to visit used book stores and a plea to give cartoon books like this a second glance.

It's a slim volume, consisting solely of wry comments on technology in the form of cartoons. It's thin enough to get through in a single sitting, and while the jokes won't have you visiting hospital with cracked ribs, they will probably bring a smile to your face.

These comments pertain to this particular book, of course, but I think they probably apply to many if not all such books.

Are they good value for money, these books? Strictly speaking, not really. At least, I tend not to buy such things for myself. On the other hand, as a small gift for the geek in your life, or a little extra on top of their main present from you, a book like this can be a nice touch.

Here's the link to this particular book on Amazon, just in case you can find a decently-priced used copy: Computers: They drive us crazy!
