I have a 14" MBP M4 lying around unused, but yesterday picked it up to have my daughter watch her evening cartoons and at 1.6kg it struck me how light it was. The Zephyrus G14 that's also collecting dust and weights essentially the same also felt handy (just can't ever start from 0% battery powered via PD).
Neither fits in the palm of one's hand, but how often is that a problem really?
If you're on a long journey, it's even more of an issue.
This is definitely not the case with my 1.23kg Macbook Air.
