Nah, you've guessed right - I would like it to be more common for kids to use their electronic devices for learning, creating, and generally solving their own problems (instead of creating them). Computing is a complex, but a very powerful tool; quite a lot about it is mindset, not skills.
I completely agree that carrying too many books is a problem. We have that in Poland, too - the amount of books kids need to bring to school is only ever increasing, and publishers are doing their best to kill off solutions like ability to share books or keep them at school (through structuring the material to be single-kid-use, throwaway, and changing every year to make people buy new copies).
That's a long topic, but school publishing is one of the industries I'd love to see completely destroyed - not disrupted, but literally all major publishers going bankrupt - and rebuilt anew, with products and practices more akin to what my country saw in the 60-80s - good books with lots of content, little fluff, reusable, resellable, and quite often usable for learning without supervision.
