Tell that to airport check-in staff haha. A laptop and charger are around 3kg and there's only so much clothing I can take out of my suitcase and wear to make it passed check-in.
But I hear you. It's annoying that I can't reuse perfectly good hardware, but it's fine - we make do.
The added scrutiny at some border crossings can be problematic too. Explaining to the inspectors at the Turkey/Bulgaria border why I had two phones and two laptops (and dissuading them of the suspicion that I was smuggling electronics to friends/family) through language barriers was a pain.
