Casio Exilim EX-Z3 £299 (www.casio.co.uk ). The most important factor in taking a photo is simply having your camera with you, which is where the oh-so-slinky Exilim range swings the bat hard. Imagine a silver credit card 23mm thick and perfect for persueding mum to slip her in handbag when you can't be bothered to carry a camera. Yet somehow, this puppy packs 3.2 Megapixels, a 3x optical zoom and even squeaks in a 2" LCD screen.
