But you're still not getting the point. I don't have anything against them voiding the warranty if you get in there and install modified parts. Most consumer devices have this clause. But it's not a matter of voiding a warranty, M$ takes it a step farther and tells you you're not allowed to change the box even if you are willing to give up the warranty. You basically will become a criminal if you open the box and modify it.
In other words, when you go in and purchase the box you do not actually own it. Just like software, you don't own it. Just like music CDs, you don't own them. Just like videos, you do not own them. Now it has spread to hardware. This should not be allowed to happen.
