ThinkPad 8 works with an optional keyboard base like Desktop, on its own as a tablet or with a Quickshot Cover for use in Tent Mode. Output to an external monitor works through a microHDMI jack while media can also be shared wirelessly via Miracast. Pricing starts at $399 with availability later this month. Lenovo also updated its flagship ThinkPad X1 Carbon laptop: A super-light and thin ultrabook that’s packed with power in the form of fourth-generation Intel Core chips. Although the laptop has a 14-inch display, it weighs just 2.8 pounds due to the carbon fiber casing and 0.68-inch thickness. Even so, it runs for 9 hours on a charge. Better yet, the Carbon X1 regains 80 percent of its battery charge in one hour. Look for the device later this month with a starting price tag of$1,299.
