The XPS 13 ships with either Ubuntu or Windows pre-installed and is a top-of-the line ultrabook, with specs similar to the Macbook Pro 13", but half a pound lighter.
Pro Great online customer service
Dell's customer service is one of the best in the industry. Especially the online customer service website. There you will find frequently asked questions which usually solve 90% of issues, if that's not enough, there's a live chat with a customer service representative, who are usually very helpful and very understanding about every issue that may arise.
Pro Stunning display
Before buying you can choose between the 4K UHD- or full HD-resolution touch displays or a full HD non-touch one. However, Linux compatibility for super high resolution displays can be spotty at times, so you might be better off sticking with the full HD if you plan on running Linux.
Display quality is very good as far as viewing angles, brightness and color reproduction go. It also has a very small bevel so the screen goes more or less edge-to-edge.
It also has an output of 400 nit, putting it in the "really bright" category as far as displays go. As for color reproduction, XPS 13's display produces an impressive 107.2 percent of the sRGB color gamut.
Pro Uses an SSD for faster operations on disk
Using an SSD greatly increases performance for every I/O operation, especially compared to laptops that use an HDD. The laptop will boot faster, programs that need to read and write to disk will run faster and scripts will compile much faster than on an HDD.
Pro Great Linux support
You can configure the XPS 13 to come with Linux out of the box. Even if you pick the Windows version, the XPS 13 has Linux drivers for all of its features and most users have reported that the whole process of installing a Linux distribution on a Dell XPS 13 is very simple.
Con Not a great choice for people who use their laptops to game as well
The Dell's integrated graphics are very poor for gaming and you won't be able to play graphics intensive games on it at all. A latest-generation AAA game will run at about 20 FPS with lowest settings. While a less graphics-intensive game such as Dota 2 for example will run at 30 FPS with lowest settings.
Con The touchscreen reflects light making it hard to see unless the lighting on the display is properly set
The screen for the touch-screen model is glossy instead of matte (non-touch screen). For what is a Linux notebook this does not make a lot of sense since most Linux users are the more tech savy who program. A glossy screen is more for multimedia, something Linux is not really known for excelling in.
