I want to answer trying to interpret the GP. For me, I want to be able to tinker with Plan 9. I love everything I have read about it. But I also need a practical environment where this is possible. I would love to be able to do minimal (frugal?) development work on a pi running Plan 9, but the lack of a browser, an editor that feels familiar (at least for a while, until I learn the ropes) and the languages I want to tinker with, it is very hard to get going.
