I find it somewhat weird that Apple allows the new iPhone 6 Plus to do upside down home screen orientation unlike previous phones. I completely understand the use of landscape view but this?
What do you mean? I always found it annoying that it /wouldn't/ turn upside down.
It makes no sense if you're using it as a phone, no, but imagine you're using it as an iPod or something, or to watch videos; I would rather have the speakers facing up toward me in that regard, and would like to be able to use the screen right-side up while I do so.
