Time was, giving a presentation meant smacking a chalk board with a long piece of cane. Nowadays it’s all sharp suits, convention halls and something shiny in your hand - which is where Logitech’s £120 Spotlight comes in. Hit the button and, rather than a little red laser dot, you’ll get a highlighted or magnified focal point on the screen. It’s clearer and can be seen by your conference call chums, too. Better still, a 30m range means you can stroll through the audience with the reckless abandon of a presenting rock star. It’ll even vibrate to keep chatterboxes in their time limit.
