Bumping this since I noticed Hanselman's blog entry shows how to create a shutdown tile on the start screen, which is nice to know.
That's handy. But this reminds me of when MacOS X Lion changed the scrolling direction of the trackpad to better match that of the tablets despite literally noone asking for this or even thinking it was a good idea after the fact. I'm like "thanks for the blog post, but I'd prefer not to pay for an OS upgrade and then have to google a solution to un**** the dumb UI changes in it". I'm still using Snow Leopard on my Macbook
