I want something I can easily carry with me. You're not wrong in that it's mostly impossible to modify these devices, but I don't think being able to mod these devices really provides you with a ton of lift anyway. And I'm okay with getting my hands dirty, but I'm just one person with hopes and dreams. Maybe I can write one kernel module but I don't think I could build everything needed for a comfortable experience.
