Why is that wrong? I also applauded (internally) when notifications were added because it was a feature that I wanted and I didn't care that Android had it before because I wasn't using an Android phone. I bought all of the Google-branded Android phones when they came out and I still preferred iOS and the iPhone so having that feature was worthy of applause for me. I don't see how the wallpaper thing is any different. As much as I would like to have had the ability to change wallpaper before then, that wasn't as important as all the other things I cared about more.
