Thanks to the pen I've also banned the last sheet of paper out of my ashes Unit in the battle for sustainability. And if I still have to write something on paper, a well-functioning pen with two additional mines is included in delivery.
Oh, on the iPhone 4 does the pen as well, as described above.
Update: And if I look at the pictures up there, I got a completely different pen. I have no cap on the pen. It is a normal pen, the one extends by turning and at the upper end is just the cap for capacitive inputting on the tablet.
