Ranked in these QuestionsQuestion Ranking
Pro Built with security in mind starting from each chip placed onto the motherboard
Pro Optional physical kill switches for microphone/camera and wireless/bluetooth
Pro Good connectivity
3 USB 3.0 (one being type C) and 2 USB 2.0 with the HDMI feels very nice to have on such a lightweight laptop. Sadly no Ethernet port, otherwise it would have been perfect.
Pro Good keyboard
Keyboards are usually bad on laptops, companies reusing small version ones on bigger size laptop with big paddings. Purism managed a good quality and use every bit of space to get a keyboard that feels good to use.
Pro Runs privacy focused software
Librem runs PureOS, a privacy focused operating system, and runs software that respects your rights.
Pro Good Linux support
Dell offers Ubuntu 14.04 as one of the preinstalled operating systems. It works right out-of-the-box and has no apparent problems.
Pro Quality Ultra HD screen
The Ultra HD screen is attractive. On it you can experience precise color reproduction with 100% of sRGB covered color space. It is an anti-glare matte display which allows the laptop to be used outdoors during daylight, even though it has a rather low brightness of 270 nits. Thus it can be an adequate display for digital artists who need to make various adjustments on-the-fly.
Pro Performs the best in specialized tasks
Workstation computers are made to run specific intensive tasks which require powerful hardware. To achieve the best results they are equipped with components that are powerful and are specifically optimized for certain applications, like AutoCAD or 3D Max. Along with its potent processing units, it also has a very large RAM with 64GBs to allow for very large projects to be run.
This laptop spans the middle range of workstations in terms of performance. On the SPECviewperf 12 benchmark application it showed a score of 42 frames per second during its 3D Max testing.
Pro Viable for gaming
The hardware is able to run modern games. Even though it’s a workstation type laptop, it can still run games like Rainbow Six Siege above 60 frames per second as long as you’re fine with sacrificing some image quality.
Con It's quite expensive
You'll be paying a higher price for Purism's commitment to secure, privacy, and freedom respecting electronics.
Con Wifi is weak
Any other laptop or smartphone will have better signal than the Librem 15. Having a strong signal is very rare (you need to be in the same room within 10m of the router), it is still working but a Ethernet port as back-up would have been very much appreciated. This is probably due to the FOSS constraint for the hardware.
Con Speakers are bad
The sound feels really wrong, the trebles are way too high and there is no bass.
Con Touchpad not centered
Touchpad is not centered due to addition of little used numeric keypad keys on the right.
Con Several things missing from the base model
The base model is quite cheap but is also missing numerous components. Each additional component requires an extra cost which, when summed, can raise the price considerably. The additional features range from something as basic as a webcam, a Thunderbolt 3 port, and a backlit keyboard to something more advanced, like a Smartcard reader or a fingertip reader.
Con Short battery life
It has a very short battery life. It runs for only 4.5 hours while idling, which is exceptionally short, even for an Ultra HD screen. It's worth noting that it’s only slightly worse with general usage - around 4 hours of use.
Con Can be really expensive
The base model is not that costly but if you’re looking for more powerful hardware, the price tends to skyrocket.
Con Low brightness with the Full HD screen
The screen’s low brightness output prevents it from being comfortably used during broad daylight. The brightness is measured at just 220 nits.
