It's really cool to be like, "I don't like how this works. I'm gonna just change it." I don't need to wait for a firmware update to get pushed out. I can just do it.
I know I have the requisite skills and knowledge to do that and most people don't, but it's still really neat to be able to do that with a device that isn't some niche thing.
Seriously, it would be sooooo cool to have this kind of support for modification with things like my phone, TV, car, microwave, etc.
