I’ve wondered if, should Apple come out with the hypothesized Mac Tablet device, whether it would possibly have a dual-screen element to it. that is, opening a clamshell would allow for use like a conventional laptop (but with a touchscreen as keyboard), holding vertically would allow for reading like a conventional book, or opening all the way (Chen’s “fanning” mode) would allow more traditional tablet interaction. We’ll see if that ever comes to fruition.

Anyway, thanks for the writeup.
