I understand the sentiment. I've felt dismay at seeing many generations of personal and work laptops turn into e-waste. It just isn't practical to keep them operating and relevant. Laptop LCDs used to be more trouble with fluorescent backlights, but since the switch to LED backlights, I've seen laptops (and smartphones) look nearly identical on their last day of service as their first. For me, it is the battery or motherboard+thermal solution which seem consumable and prone to failure. If these were modular and could always be replaced with contemporary upgrades, I could easily see myself using the same screen and chassis for decades. The basic 14 inch ultrabook format is close to its asymptotic ideal, I suspect. This could even justify having a little more invested in the chassis to make it even more robust, such as some more exotic titanium alloy or whatever. But, for me the supported service life would really need to be decades with compatible modular parts. I would not want to be stuck looking at obsolete replacement parts from somebody's dusty warehouse when I have the need or impulse to refresh the machine. I'd want the replacement module to have options with the now current CPUs, GPUs, RAM type, networking, storage, and other IO ports. I would not want to be operating a time capsule of obsolete components.
