I got to play with a Purism Librem 14 machine last week, and the first thing I noticed was how heavy it was. The build quality seemed fine, but compared to a nearby M1, there's no contest about which one had the better build quality. When giving the machine back to its owner, one of the rubber feet on the Librem 14 simply fell off in my hand.
Thinking maybe it was a fluke, the owner of the machine fiddled with one of the other rubber feet, and was able to get it to pop off just by flicking it with his finger.
The security features are nice on the Librem, but as configured, this particular laptop cost more than the M1 Macbook Air. Same amount of storage, same amount of ram. Different CPU's, obviously.
When asked about battery life of the Librem 14, the owner said he hadn't really seen how long it'd typically last on the Librem. I can say though that the M1 Macbook Air, during my normal use (writing and compiling code, slack, email, zoom, etc), is having a bad day if it doesn't last at least 6 hours. I've used the M1 on a trip recently that took 38 hours, door to door. I didn't charge the M1 once, and used it quite a bit during various flights and while waiting for flights. I worked, watched a couple of movies, had a couple of Facetime calls. I still had 25% battery when I finally arrived.
While I admit that it's probably not fair to make a judgment after holding the Librem 14 for about five minutes, I can't really say that the quality of the Librem 14 rivals that of Apple.
Edit: forgot to add. I've rarely felt my M1 get even warm, let alone turn on a fan. My Macbook Air doesn't even have fans. I used to be able to count on the Intel based Macbooks to warm my fingers during winter, but not any more. The M1's run very cool. The Librem 14 was loud. And hot. Not warm, but hot. My fingers were sweating when trying out the keyboard.
