"The OS is the Free Software Foundation endorsed by PureOS, a Linux distribution that, in this case, has been reworked with a mobile UI. Purism says it will provide updates for the "lifetime" of the device, which would be a stark contrast to the two years of updates you get with an Android phone."
"Selling a smartphone is a cutthroat business, and we've seen dozens of companies try and fail over the years. Purism didn't just survive long enough to ship a product—it survived in what is probably the hardest way possible, by building a non-Android phone with demands that all the hardware components use open code. Making it this far is an amazing accomplishment."
