Liquid Leap: introduction You probably know Acer for its good-value laptops, but with the Liquid Leap it's having a crack at the big noise in lifestyle tech: wearables. The Liquid Leap is a fitness tracker with a hint of smartwatch functionality. At £80 it's not a price for a band with a full display. However, with a fiddly fit and only surface-level features in each of its areas, it's best used as a simple watch and pedometer.
