2-in-1 laptops have come a long way over the last few years from their bulky and clunky methods used to transform predecessors. Lenovo has perfected it's back flipping notebook with the Lenovo Yoga 3 Pro, sporting watchband hinges that practically blend in with the rest of the laptop's chassis. Likewise, Microsoft finally hammered out nearly all of the kinks out of its laptop-tablet concept with the Surface Pro 3.Now, Asus attempts to one up everyone with the Transformer Book T300 Chi, one of the thinnest 2-in-1 machines ever created. Like the Surface Pro 3, this machine's guts are stashed behind the screen, which lifts away from a Bluetooth keyboard base to be a standalone tablet. But by going with a fanless Intel Core M setup, Asus has brought us a convertible laptop that's even thinner than some tablets. Don't mistake this machine's svelte profile for lightweight performance, though. This machine can run with the best of them, but it might be best suited for media lovers.
