Is anyone surprised? I know I was claiming it to be a flop. If it's not selling better than the iPhone 4S at this time last year then why bother making a whole new device instead of just demoting the iPhone 5?
Oh Apple. Either you're losing your way or you've created another device to join the G4 Cube, ping, and many other failed apple devices.
These numbers don't actually tell us if it's selling better than the 4S... It's just a ratio... Both the 5s and 5c could be selling like hotcakes, or both could be doing poorly. The ratio doesn't tell us which.
You can pretty much read into these numbers anything you want because for one to go up, the other has to go down. With no actual numbers there's no way to get a perspective.
