If carrying bags of stuff is not really a problem, then as things get smaller, we carry more of them.

What do I carry? Laptop, paper notebook, my lovely noise cancellng headphones, a charger, an external battery for my phone, a usb charger, some bits of paper. Some times I add a tablet or kindle to the mix. Other times a raspberry pi or other embedded device.

I obviously prioritise having enough tools with me to work anywhere I like with maximum comfort.

Its all a matter of priorities.
