I usually buy the non plus versions of the iPhones because they are easily to keep in one of those belt cases that loop on your belt. Wouldn't the iPhone X or 8 Plus be too big for this? I can see if you carry a bag or purse with you it would be easier to store away. But I don't. And the iPhone X is supposedly just a little smaller than the 8 Plus. I wish they made Plus and non Plus versions of the X version too.
