If, like me, you're new to Ubuntu, then this looks like a handy, easy to use guide to the basics. Essentially it is, but it also leaves you feeling like a right muppet when you realise that it's the printed version of the help text that comes with the Ubuntu install. It's exactly the same and gives you no more or less than what's available when you click the help icon in the toolbar. I guess it's more convenient to read, because it's a book, and if it was 5.99 or similar it might be worth it. But when you pick it up, look at the invoice, groan quietly to yourself, you'll wish you hadn't bothered.
