As the topic states, what is the biggest reason for you to jump over to the bigger iPhone Plus? For me, the plus's camera with OIS is the biggest factor. I am really on the fence and I just have this feeling Apple is going to make all iPhone Plus 5.5'' owners who would have preferred 4.7'', by releasing the "iPhone 6S" next year with OIS built in. I would prefer not to have to "get used to the 5.5''" size just to switch back to the 4.7'' next year because of the camera OIS. With the iWatch requiring the iPhone, it seems to make sense to have a smaller device to go running around with than a big 5.5''. The landscape mode is nice too, having a more "portable" iPad Mini, I am surprised not many people vote for it as that would have been my second reason.
