I think you’ll be quite a bit happier. Between the quality of life stuff like the ancient life sensor, the pure quality stuff like a better screen and speakers, and extra RAM so it lasts longer that seems like a good decision.
The Neo is neat and for someone who mostly does surfing and standard office work kind of stuff I suspect it’s a pretty great little laptop for way less than Apple usually charges.
But it’s not going to compete with an M5 anything.
