I may be a zealot or a fanboy with blinders on; however, I truly think this device is amazing. Is it objectively “better” in terms of technical specs and functionality than and Android or Iphone? No, probably not. However, whether it is objectively “better”, in this respect, is not the question, in my mind.
The real question should be: is the Librem 5 objectively a better freedom respecting and privacy respecting device than those made by Google or Apple? The answer there is unequivocally “yes”. The real value (making it worth $1,200 - $2,000) is that someone is taking on Goliath companies who sell devices in “walled-garden” ecosystems that are ostensibly there to “track” you and make money from it. I personally find that appalling, frustrating, etc. (Use your favorite adjective).
The Librem 5 can do, more or less, what you ask it to do. It respects you. There are dedicated people at Purism, developers, outside volunteers, etc., who are working this phone, I suspect, because they believe in freedom and privacy. It is important. It is also an uphill battle.
In sum, the device is very capable, not perfect, but very cool and useful. Maybe most importantly, it is freedom respecting and mostly private (the “un-private” aspects are user-driven). Just like any other important social endeavor, I believe society “should” support the aforementioned individuals, volunteers, companies, etc, who are advocating for freedom and privacy.
That is the “Pro” of this device. The only real “Con” is that you can’t get all the fanciness that many (including me) were previously used-to. Of course, as we all know, that “Con” and fanciness comes with the unacceptable price of freedom and privacy - thus back to my original conclusion of the “Pro” of the device.
