We tell the detailed story on the product pages: https://frame.work/products/laptop

We've built a 13.5" notebook where every part of the hardware is replaceable or upgradeable by the end user. That includes memory and storage, which are increasingly soldered down on new laptops, but also the entire mainboard to be able to move to new CPU generations. We've done this without sacrificing performance or form factor. We use 11th Gen Intel CPUs and the product is approximately the thickness and weight of a MacBook Pro 13-inch.
