Lenovo sells a lot of black boxes. At CES 2015, as it announced that it’s sold 100 million ThinkPads, Lenovo also refreshed much of the lineup. The upgrades start with the X1 Carbon, which has been for a couple of years one of the best laptops on the market: the 14-inch laptop now comes with Intel’s fifth-generation processors (the long-awaited Broadwell), plus faster solid-state drives and plenty of new business software. It still weighs less than three pounds, it still has that awesomely rugged body, and it has a brand-new high-res screen. The new model starts at $1,249.
