For those who haven’t upgraded to the iPhone 5, allow me to illustrate why apps on the iPhone 5 that haven’t been updated are frustrating.
See the difference in positioning of that keyboard? That’s the cause of many typo’s and muscle memory confusion. Can’t unlearn the old way, can’t learn the new way. Generally speaking new device, new feel, you pick things up pretty quickly.
I don’t mean to pick on Google here, they aren’t the only ones who have yet to update, it’s just the first one that came to mind.
