When there is nothing exciting to note about your own product...
I don't know. A headphone jack is a more exciting feature than anything the X has to offer.
That being said, the primary design objective of Android is to siphon as much personal information as possible from the people ignorant enough to use Android and deliver it to google and anyone willing to pay google. It is just scary how bad Android is.
So for that reason alone, at this point I don't see myself leaving iPhone ever. But aside from privacy issues, iPhones really are boring, lacklustre products. Especially next to the features Samsung is rightfully bragging about.
