"But it isn't. As I write, I have a Fairphone 3+ on the desk beside me. It's a very capable, nicely designed, dual-sim Android phone. In just seconds, I snap off the back of the case with a fingernail and remove the battery. Other modules of the phone, including the camera, can be removed and replaced without elaborate tools or expertise. And once it's done you snap the case shut and press the power button. And you can buy it online for £399. Over in the US, the Framework laptop has just come on to the market. It's a thin, lightweight, high-performance 13.5in notebook that can be upgraded, customised and repaired in ways that no other notebook can. It's even available as a kit of modules that users can change and assemble themselves, installing only the modules they want as plug-in units. Think of it as Lego for geeks."
