Ranked in these QuestionsQuestion Ranking
Pro Very light and thin
Weighs just 1.31kg and is 17.7mm thin.
Pro Good 14" WQHD IPS display with touch and non-touch options
Sharp 2560x1440 IPS display for the touch screen version. The full HD 1920x1080 display for the non touch version is shockingly mediocre (almost no viewing angles work) and should be avoided at all costs.
Pro Good keyboard, trackpad and trackpoint
The keyboard has all keys in the expected places (unlike previous models) with a nicely sized trackpad that has two seperate left and right click buttons with the trackpoint also making the return in this newer model.
Pro Linux friendly
Pro Good battery life with rapid-charging
Estimated battery life of just under 11 hours of typical use. Rapid-charging technology allows charging 80% of the battery in 30 minutes.
Con Computers may have man-in-the-middle adware installed
Lenovo is shipping computers preinstalled with man-in-the-middle adware called Superfish. It's a web proxy that can hijack any web session, including encrypted/https sessions. And since the root certificate is the same for everyone with private key present on the machine that's now publicly known, anyone can spoof any site to people using Lenovo laptops. Currently, it affects IE and Chrome browsers with Chrome expected to push an update that will block the certificate soon.
Uninstalling Superfish won't remove the certificate.
Lenovo are standing by their choice to install adware.
Con No SD card reader
There is no SD card reader in this device, something that can be found in competing device such as a Macbook.
Con Poor build quality
There is no shortage of reports from owners (or former owners) claiming about the cheap quality of their X1 Carbon. Complaints include faulty screens, and loose cases.
