Sure, I _could_ carry more weight, but I'm not sure why I'd _want_ to. Why should I sacrifice for example an extra pair of socks or a shirt, when I don't need to? Having a bigger screen or a faster PC doesn't matter more to me in light of that space and weight trade-off. I use a code editor from 1992, a programming language from 1989, and a tiling window manager with no frills. An N100 is more than enough.
If you can hike all day there is no way you are weak enough for this to even register.
