Microsoft's Windows 8 didn't just shake up the company's entire software empire, but the mobile computing industry to boot. Given the dualistic nature of the new Windows, laptop and tablet makers responded in kind with devices commonly known as 2-in-1 laptops, or hybrid laptops.These are devices that are able to serve as both a laptop and a tablet, either in a detachable design that sees the touchscreen doubling as a tablet, or a convertible approach in which the notebook's hinge rotates 360 degrees for a similar effect. In the past, neither have been all that successful in providing both experiences in equal measure, but that's slowly changing.Considering their similarity to Ultrabooks in terms of build quality, thinness and lightness, 2-in-1 laptops are generally priced in the same range: between $700 (about £450, AU$800) and $2,000 (around £1,169, AU$2,131). These are sleek, powerful devices that look good and serve multiple use cases to varying degrees of success. With that, here are the best 2-in-1 laptops that we've reviewed thus far.
