I've stopped carrying my laptop everywhere, unless I plan to work. Otherwise I just leave it plugged in on my desk.
Instead, I carry a very light bluetooth keyboard and my Moto G5 phone. The laptop exposes SSH and Mailpile over PageKite, and I've got Termux on my phone... it's not quite comfy enough for coding, but when I need to do some quick e-mailing or emergency admining, this is quite adequate.
My laptop has effectively become my personal "cloud server."
Which I think is pretty cool.
