I don't own an iPhone, but I played with one extensively on two separate occasions. It occurred to me that the device is not ideally operated with one hand, as an iPod is and most other cellphones are. The location of the home button, so far down at the bottom, makes it awkward to access with a thumb while holding (and typing is definitely better holding with one hand/using the index finger of the other), and scrolling the iPod part with a sweep of the thumb is, again, less than ideal. The way multiouch controls everything, you are limited to your thumb if you are holding it in one hand or using two hands (well, one hand and an index finger). I think a better arrangement would have been to include a side-wheel -- similar to a Blackberry -- that could not only scroll but also be pushed for home (or pushed for select?). This in addition to the standard multitouch for people who get along with that with no problems. It would make the thing easier to operate singlehandedly. Any owner/operators agree?
