The ultimate business convertible? Want a high-quality business laptop? Lenovo's ThinkPad X1 Carbon has set the benchmark, but this is a fiercely contested area of the market, with multiple manufacturers eager to lock down lucrative enterprise contracts. HP is one of the biggest names in the business and has seen great success with an Elite line of PCs promising "a unique combination of durability, reliability, security and efficiency."

Striving to create "the world's most reliable computer," HP Elite PCs are subjected to severe temperatures, high altitudes, and drop tests you wouldn't want to try out at home. Testing is said to continue for more than 100,000 hours, resulting in products that offer genuine appeal to IT managers and road warriors alike, so while the likes of the Spectre x360 may hog the limelight, there's usually an Elite alternative for those demanding extra toughness.
