at the same time, I personally don't see what all the fuss is about. you can upgrade both DIMMs, which is cool, but not exactly unheard of these days (I guess it's getting there in an ultraportable?). you're still stuck with DDR4, which is almost EOL, and the max capacity it entails. it's neat that you can customize your IO options, but how many people are going to do that more than once? being constrained by the chipset, it's not like you're going to be able to "upgrade" your IO in the future.
the most likely parts of a laptop to fail are the SSD and the battery, both of which are fairly easy to replace on almost all laptops. past that, you aren't really gaining that much when you're locked into whatever CPU/chipset was current when you bought the laptop.
