I am both amazed and terrified. I'm amazed that we're in an age where the processor I'm using to do all the things I do has it's own processor that's running it's own OS, has a Webserver and running a Java stack. I'm also terrified about what this processor could do at any moment. Is there away to inspect the IME bytecode to see if they put any backdoors in there? How is this code updated?
