149: Eye Phone

Explanation
In the original comic, the man at the desk complained about changes to the UI (user interface) of an app he was using, which made his tasks more difficult, perceivably for no good reason. His offscreen co-worker then told him he would not like getting old. (The meaning of this is debated and probably outside the scope of this wiki. See the appropriate xkcd Explained article.)

This comic keeps only the first line of the desk worker's dialogue, and takes advantage of the all-caps text to interpret "UI" as "Ui", Ui being a character from the K-On! franchise. The author added the xkcd Phone 4 from another strip, which parodied the iPhone line by depicting the phone with dubious features (for example: laughable specs, pointless apps, parts better suited to other products), and puts Ui's face on the screen, but with an arbitrary change: the eyes of her friend Jun Suzuki. He also altered the phone that the man was holding to be an xkcd Phone 4, by adding the "wings". Additionally, the title is a pun on iPhone.

The author writes:
Original xkcd strip: 1770: UI Change. Phone from 1707: xkcd Phone 4.
