Hrmmm.......I know this will sound like sheer geek-dom/fanboy madness, but a few weeks back, I made a crude cardboard mock-up of the thing (actual dimensions - 7.47" x 9.56" with paper screen laid on top) to get an idea, ergonomically, what this would feel like while holding. Albeit, not the real deal, I'm convinced the best way to dispatch quick emails and instant messages on iPad (sitting or standing) will be in portrait view using your thumbs to type. I have my doubts about landscape orientation for typing - unless seated as in the guided tours or on a hard surface. We'll know for sure in a matter of hours.
