Convertible 2-in-1 laptops with 360-degree rotating screens are common enough these days, but Lenovo's Yoga 9i is a leading example. It comes in 14-inch and 15-inch sizes, with the 15-inch model starting at an eye-watering £1,899.99 (inc. VAT). My review unit was a 14-inch model which starts at a more pocket friendly £1,299.99 (inc. VAT). In the US, the starting price for the 14-inch Yoga 9i is $1,099.99.
