Originally announced at CES 2013, the ThinkPad Helix has been subject to a few revisions since. Lenovo has just teased the next one, which will see the convertible slim down and adopt Intel's Broadwell-based Core M processor.
The Core M-powered ThinkPad Helix will feature an 11.6" touch screen with a 1080p resolution, up to 8GB of RAM, storage options including PCIe solid-state storage, 802.11ac Wi-Fi, and optional WWAN. Despite that generous assortment of hardware, Lenovo says the system will be fanless—and lighter and thinner than before.
The tablet component alone will weigh 1.75 lbs and measure 0.38", and there will be two detachable keyboards: the Ultrabook Keyboard, which will boost the thickness one inch and weight to 2.98 lbs, and the Ultrabook Pro Keyboard, which will be slightly thinner, at 0.8", but a fair bit heavier, at 3.7 lbs. The extra weight will be due to an auxiliary battery, which will boost the system's maximum run time to 12 hours.
Look for the new ThinkPad Helix in early October. Prices will apparently start at $999 for the base model with a 128GB SATA SSD and 4GB of RAM. Lenovo isn't yet saying what the various premium options will cost. (Thanks to Liliputing for the link.)
