I have broken so many electronic(and mechanical) gadgets trying to hack on extra functionality, I might have been sad but I am not sorry that I had to learn something new. Mostly it is a principlet stand that my N900 belongs to me, I like to know how to access all of it's functions before it expires from natural entrophy, even if I never plan to use them.
It is like picking locks for fun, illegal to use on your neighbors house without permission, maybe it is a suspicious ability to people who do not know why I learned this skill and teach it to others including my kids, but still legal and fun to have the skills to make and use the tools on my own locks.
