[1][2] The ThinkPad Yoga series laptops have a "backlit" keyboard that flattens when flipped into tablet mode.
Lenovo implemented this design in response to complaints about its earlier IdeaPad Yoga 13 and 11 models being awkward to use in tablet mode.
Other than its convertible form factor, the first ThinkPad Yoga is a rather standard ThinkPad device with a black magnesium-reinforced chassis, island keyboard, a red TrackPoint, and a large buttonless touchpad[1][2] (but touchpad have been upgraded to a mechanical 3-button version for a next generations of Yoga line).
[3] The ThinkPad 11e is a Chromebook that has a matte black chassis with reinforced hinges and corners, a sturdy lid, and a rubber bumper protecting its display in order to help it survive accidental dropping, spills, and general rough handling.
It uses a quad-core Intel Celeron CPU, has 4 GB of RAM which can not be upgraded, an 11.6 inch screen, and 16GB of eMMC flash storage.
[4] The Yoga 14 model reportedly "strikes the middle ground between bulky workstations and flexible hybrids.
According to a review for Business News Daily, "The ThinkPad Yoga 14 is a balancing act of diverse features.
And extras like the TrackPoint pointing stick are great for legacy ThinkPad users who prefer those options.
Lenovo claims the Yoga 260 has been subject to extensive testing of its ability to survive extreme temperatures, vibrations, altitudes, and shocks.
[8] An active stylus, the ThinkPad Pen Pro, is included for drawing and text entry; it can be used with Lenovo's WRITEit hand-writing recognition application.
The P40 Yoga includes a touchscreen display with resolution of 1920×1080 or 2560×1440, designed in cooperation with Wacom, using that company's Active ES technology which can sense 2,048 different pressure levels.
Dan Ackerman of CNET wrote, "In our brief hands-on time with the ThinkPad Yoga, while it's made of tough, light magnesium alloy, it didn't feel as slick and coffee shop ready as the IdeaPad version (and it lacks the extremely high-res screen of the Yoga 2), but the hidden keyboard think [sic] is so fascinating, you'll find yourself folding the lid back and forth over and over again just to watch it in action.
There is nothing ill to speak of regarding the ThinkPad Yoga -- everything about it is solid, with the exception perhaps being a lower quality stylus than what an artist would need.
The construction feels solid and durable in the hands, the keyboard is comfortable for typing in long duration stints, and the hardware is capable for a variety of tasks.
