The ThinkPad T series isn't traditionally the prettiest out there, and it's certainly not one you'd usually see highlighted. But Lenovo went and made them pretty. It's got a new thinner body (20.6mm), a thin bezel, and a carbon fibre top with a magnesium exterior. It doesn't look quite as great as the X1 Carbon, but it's nice just the same.
The rest is, you know, a ThinkPad. Standard ultrabook guts (though up to 12GB of RAM is nice), Lenovo software, nice keyboard, 14-inch 1600x900 matte screen. The T431s is out in the US at around £700; UK pricing and availability are still on the down-low.
