Pros
Pro Good build quality
The Carbon X1 is a very light and durable laptop. It has the characteristic raven-black finishing of other Thinkpads on top of a carbon-fiber reinforced chassis. The carbon fiber increases the overall durability of the laptop, making it a great fit for people who travel a lot since it can withstand a lot of physical damages.
Pro Great battery life
The battery supports over 10 hours of light activity such as web browsing, watching videos and editing documents, which can be doubled to 16 hours by swapping in the extended, 6-cell battery, which can be hot swapped without turning off the laptop since it also has an internal 4-cell battery.
Pro Excellent display
The X1 Carbon comes in two different versions. With a 1080p or a 1440p display, with the latter being $70 more. Both displays are excellent. Images are sharp and colors very noticeable. Although, understandably, the 1440p display has images that are a bit sharper than its 1080p counterpart.
According to colorimeter tests, both versions of the display can produce 104 and 103 percent of the sRGB color gamut, respectively. That's very impressive when compared to the average for 14" displays (83%).
The 1080p screen is noticeably brighter than the 1440p screen (292nits vs 257nits) and the colors generally start fading only at about 45 degrees viewing angle.
Pro Excellent typing experience
Like most Thinkpads, the X1 Carbon has an excellent keyboard as well. The keys have about 1.8mm of travel and provide great tactile feedback. Their gently curved keys also make it very easy to target without looking at them. The keyboard also has optional backlighting which can be turned on or off with a simple key press.

Pro Great speakers
The X1 Carbon has bottom-mounted speakers which provide excellent audio output. The sound is loud enough to fill a large room and there's clear separation of sound coming from the speakers, making them great for any sorts of recreational activity involving audio be it listening to music, watching movies or playing videogames.
Pro Built-in support for Amazon Alexa
The 2018 model of the X1 Carbon has far-field microphones built-in to work with Amazon Alexa. This will allow you to give commands to Alexa from across the room.
Cons
Con Extended dual battery adds weight
6-cell extended battery adds 0.4 pounds to take this ultrabook's weight far above that of the ultrabook standard (<3 pounds).

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.
