3 Mycestro is a small, three-button device worn on your index finger that allows you to control your on-screen pointer, instead of a mouse or trackpad. Touch your thumb to the side of the Mycestro and wave your hand in the direction you want the pointer to move, or slide your thumb to scroll. Designed for use in confined spaces, it does take a bit of getting used to and can feel a little imprecise – plus you’ll need to raise the sensitivity lest you fall victim to wrist strain. While it has some potential, the humble trackpad is still be a better bet for now. Alex Blake
It’s certainly a nice idea, but the Mycestro needs more polish before it becomes an essential travel computing accessory.
