Now available on iTunes: HP Prime Graphing Calculator iOS app

[factor]

After reading the iTune page I found it very interesting and fine product indeed!

Just wondered does the Prime App on iOS "turn" to landscape mode? And, does it support portable keyboard?

Say when a portable keyboard is plugged in, it is then possible to hide some keys from the screen (at least the numeric ones), saving the real estate for larger screen! I am assuming the screen resolution will grow, not just "stretching" to map more screen pixels here..
