About that ... how will it be used?
1) Holding the iPad like a "book" (whatever that is) and typing with one hand?
2) Laying the iPad flat on some surface to use both hands ... and craning your head out over the screen so you can see what you are typing?
3) Propping up the iPad on a pillow or something so you can see the screen, and then angling your arms weirdly so you can hit the virtual keys?
4) Ignoring the onscreen keyboard completely and using the "keyboard dock" (sold separately) that Apple is so thoughtfully making available to those who like the device but still wish it had a real keyboard?
Apple financial analysts everywhere are betting on #4 ... the one that's not included with the device.
