I've hacked my MyBook only enough to have enabled SSH and firefly.
My understanding from reading things here is that I'll have to redo the little I've done over again if I upgrade the firmware, and restore gcc if I ever want to compile anything from source.
I understand that those things don't amount to a whole lot of work, but what reason would I have TO upgrade? I'm not unhappy with the box as it exists right now in any way. Are there any non-obvious (or obvious for that matter) reasons why ugrading is worth the trouble?
