I just recommend this app to my mother in law in lieu of one of those morbidly expansive camera bird feeders.
I like the stability of keeping my settings in the same place across devices. I do travel a lot and often adjust my data roaming, SIM card, and date/time settings (I like my phone to be on the destination time the moment the plane takes off). Mostly it has to do with keeping my priority apps on the right side of the phone, rather than in the dock—my most used apps are all in the two rightmost columns.
