The price increase and subsequent quality increase of the X made the purchase make sense given that it would be a longer-lasting phone.. on the 3-4 year timeframe rather than a 1-2 year timeframe. If they didn't refresh the X (kept the name) and just released the larger and cheaper versions, it would have made sense. Given the diminishing returns and higher prices, they should put more time in to make sure they have breakthrough releases. Even Jobs did this with the tick-tock of the 4/4S. The naming scheme is all messed up
