It also will boast a faster GPU, and there will be an option to select Intel Iris Plus Graphics 640, which will support 4K video rendering. The 2-in-1 also has a Thunderbolt 3 port and an HDMI port to connect external 4K displays. Additionally, the device comes with two USB 3.0 ports.
The 2-in-1 includes a pen, which takes advantage of the new inking features in Windows included in the Anniversary Update. The pen is becoming an important part of Windows devices, and it's much easier to take notes and draw on the X1 Yoga, Bhatia said.
The X1 Yoga can be configured with a full HD screen of a 2560 x 1440 pixel display. An OLED screen at 2560 x 1440 pixel resolution will cost you more, and that configuration will offer a battery life of about 11 hours.
Finally, the multi-purpose ThinkPad X1 Tablet, which stole the show at last year's CES, also got major upgrades. It's a detachable device that turns into a laptop with a keyboard module, or can create a 60-inch projection display when a projection module is attached. It has a 12-inch screen that displays images at a 2160 x 1440 pixel resolution, a storage capacity of up to 1TB, and memory capacity of up to 16GB.
It weighs about 767 grams, and now has a battery life of up to 10 hours and five more hours with an additional module. It has a USB-C port, a USB 3.0 port, one Mini-DisplayPort, a nano-SIM slot, and a micro-SD card slot. It has an 8-megapixel rear camera and a 5-megapixel front camera.
The X1 Tablet will ship in March.
Wireless features on all X1 devices include 802.11ac Wi-Fi, Bluetooth. Optional Wi-Gig chip and NFC are also available on the laptops.
