While this does have the name of iPod and iPhone, this effect should cover all devices (Android, webOS, and....) with simplified OS which focuse more on the user friendly interface than handing multiple complex programs/functions.
I can understand why the study was done on Apple device due to its popularity.
However, due to the nature readers in this website, I am having kind of feeling that the autor in TG intend (or tend to) make Apple news looks bad to please the readers and draw more people reading/leaving comments on the article.
While I can understand the intent, when TH/TG is trying to gather the crowd by the hot spices instead of real beef... that kind of bring the level of TG/TH down.
Anyway, the authors in the TG/TH should know better about their readers here. I will be surprise that this kind of wording on the title and artile were just a "frequently happened accident".
