I checked out the Lenovo Flex 13 at IFA earlier this month (video below) and it was good to see efforts in the Ultrabook space trickling down to mainstream laptops, because that’s exactly what the Lenovo Flex is all about. It offers Ultrabook-like specifications in a multimode (laptop + easel) design. Pre-order for the mobile 13.3” version isn’t available yet but the 14-incher is up for $669 in the US (Core i5) and €499 in Europe (Core i3.)
