You mean like the Serval? Or the Gazelle, if you want a slimmer version of the same thing? Both have upgradeable RAM, lots of non USB-C ports, and replaceable batteries. Both are quite handy systems.
Serval is very dated, but the Gazelle is darn "close" to a nice modern look & feel... for a Linux laptop it's about as close to MBA as you're gonna get. But overall I'd agree an "across the board" update would be most welcome. S76 makes great hardware and their design aesthetics have been steadily improving, I'd keep an eye out here, don't discount them.
With the circa-2009 Acer plastic look? Big plastic air fins, feet that stick out the bottom to stop it sliding into t bad properly, huge (huge) bezel around the screen?
Currently they laptops are based on clevo devices with lots of work added on top. But they stated that laptops will be the next step after desktops. Just don't hold your breath as it gets a lot harder at that form factor
