Leave it to big corporations like Microsoft to make it as difficult as possible to run homebrew apps. Seriously, I imagine they must be almost as bad as Sony. Homebrew apps = more computer sales.
That's why I like hackers, as well, as they are able to fight through all the crap large corporations put in front of us.
Also, I found out the hard way this weekend that secure booting is nothing but bad news, as it gives Microsoft even more control over YOUR computer, while at the same time preventing such basic things as loading recovery disks (but most of you guys probably already knew that).
