So it ends up being rare that you have the laptop plugged in while you are actually working with it.
The MacBook 12 is probably the best laptop I've owned even if spec wise it was a downgrade from the MacBook Pro 13 I was previously using.
It's compact, extremely light, the keyboard is okay-ish (you get used to it), the display is the best I've ever seen anywhere on any kind of machine, and the battery longevity for casual browsing, some video/music, and coding, is out of this world. It can easily last me at least 6 hours of medium usage; if I use it sparingly (not much video for example) it can easily go to 8+ hours.
I have nothing bad to say about this laptop. The keyboard could've been slightly better but at the thinness of it, it's pretty adequate.
