How Are You Holding Your iPad?

Before it was announced, we mocked up a crude iPad to test some basic tablet ergonomics. It was awkward! (And oddly sensual!) Now that I have my iPad, I still don't know: How are we supposed to hold it?

Our original mockup might've been a little off - our aspect ratio was closer to widescreen than the iPad's, and we assumed there would be a smaller bezel - but it was close enough to get the point across. The point, of course, is that there are very few graceful, sustainable ways to hold a flat piece of glass and metal. Apple's folding case helps a bit, but it's a crutch. So, commenters, how are you tableting? Or just as importantly, what ways did you think would work that just... don't? [Tablet Sutra]
