It's more than 1.7in thick, weighs more than 4.5 kilograms, and apparently has the world's largest laptop screen space. As odd as lugging a 4.5Kg laptop around sounds, it actually makes some sort of sense when you think about it. Sure, there are now plenty of powerful laptops that can replace a desktop PC. But for some of us, it's never the same as sitting in front of a PC. Especially if you're used to having two screens. Someone must think there's a market for the twin-screen laptop — this isn't the first. Lenovo brought one out a couple of years ago. Given the number of people who prefer multi-monitor setup, surely someone can come up with a lighter, less cumbersome, and cheaper design?
