Not really surprisingly, it is quite hard to get a mobile Linux handheld device in 2019. You either have to build your own or try to get your hands on the (discontinued) obscure ones. Would computer manufacturers sell you a device that lasts you 10 years? It is not really profitable from the seller’s point of view.
Owning a Linux handheld computer can help you detox from harmful Social Media experiences; using FOSS also means getting rid of bloatware or walled gardens like Android, iOS, MacOS or Windows. This can allow you to run top quality creative software without spending a cent, on hardware that is relatively really cheap!
Also, if you are a daily GNU/Linux user like me this will ease integration between your devices. I’m planning to use the same distro, Void Linux, on every device I own. My desktop, my laptop and this handheld 🙂
Building a General Purpose Linux Handheld can be a fun and educative experience. You also end up with a device that your kids, parents, friends or sysadmin can enjoy for everyday tasks.
