I don't really understand the point of this article as "redesigning the laptop." Nearly all of the things they mention is either software (e.g. better processing of mic input) or called a desktop (screens, noise, etc.).

If I'm not doing something that requires huge wattage, the only thing a desktop computer does is to force me to sit at a desk 100% of the time I'm using it. Hard pass.
