I have no dog in this fight, because I just bought a mid-range macmini. But I was looking at the tear down of the new iMac and they use adhesive on the screen!!!! Apple just doesn't even care if you want to open it up. They have to digress in their design philosophy and strike a better balance between functionality and maintainability. If Sir Jonny can expand his horizons a little more, he would design something that a user can open and change some components.
