The funny thing is that since Apple just came up with these things it shows that common they didn't have common sense either. If it just makes sense for a 4" screen then why was the other's always 3.5" and always told they were big enough. Any bigger wouldn't make sense.
They built round earbuds but all the sudden they have common sense and made them the new shape.
I guess the maps are common sense as well. You know, not showing all the roads, going the wrong way, or placing them over water.
