Common sense is not common, in fact it's extremely rare in the wild. FYI, Dorothy's slippers were ruby. People have never been able to "do what they want with what they purchased" because there have always been, and will always be, limitations. If you don't like limitations you have to design and build your own device from the ground up, in which circumstance you get everything YOU want exactly as YOU want it. Don't be surprised if someone comes along and tells you YOUR perfect device is shyte and doesn't suit them.
