Bragging rights are a tricky thing. It's easy to say that you're the first or best, but backing up that claim is another matter. Take MSI's brand new WS60, for example. The company bills the 15-inch laptop as the "world's thinnest and lightest mobile workstation," and it's definitely on the featherweight side at 0.78 inches thick and 4.36 pounds. There's only one problem: it's actually a runner-up. Dell's Precision M3800 is both slimmer (0.71 inches) and lighter (4.15 pounds), so that's the machine you want in your bag if sheer portability is the major deciding factor.
