Following is the list of top 20 gadget of 2021: Samsung Galaxy Z Fold 3 and Z Flip 3 £1,599, £799 Cutting-edge technology is frequently prohibitively expensive, difficult to operate, and less than sleek. That is not the case with Samsung’s latest foldable screen phones. The Z Fold 3 tablet-phone hybrid and Z Flip 3 flip-phone reinventions are smooth, fluid, and even water-resistant, with large screens packed into small bodies. The Fold may still be prohibitively pricey, but the Flip 3 costs around the same as a top smartphone and is much, far more fascinating. Samuel Gibbs
