I understand that when OnePlus One was launched it was in the "Phablet" category. My point is I don't recall anyone using that label on mine (or on my IPhone 6+) because larger phones were becoming a lot more mainstream at that point.

Then we're making the same point.

The overton window has shifted so much that things that used to look ridiculous and had to be labelled as a portmanteau look ordinary today.
