Her Royal Highness, Queen Elizabeth Alexandra Mary Mountbatten-Windsor of the United Kingdom.
Apparently a big Doctor Who fan (hence why Michael Grade, who screwed it over in the 80s, is the only BBC controller not to have been knighted). Quite tech-savvy; she was the one who insisted on televising her coronation. President Obama's gift of an iPod to her was not a gaffe, as commonly believed: she did, in fact, already have one, but had mentioned it was a generation or two out of date and she would really like a new one. Plus, the royal family now has a YouTube account. This was also Her Majesty's idea.
