Apparently @Purism dropped the plan to create a pen tablet convertible - at least it disappeared from their website. Meanwhile BYOD classrooms are flooded with iPad Pros and Surface Tables without any viable open alternative in sight.
@djsumdog@Purism I also run #Slackware on my Lenovo convertible pen tables. However, generally people don't install operating systems. As long as there isn't a Linux pen tablet you can buy which works well, most people will keep using whatever came with their machine.
