To each their own, but I fundamentally disagree. And I think that the iPhone 6 and 6 Plus show that the vast populous disagrees with your opinion.

I don't have a laptop (other than my SO's), and I don't have a tablet. Most of my daily personal connectivity is 100% facilitated by my phone. I like having a screen big enough that I can run two apps side-by-side (and I regularly do), or watch Netflix in bed or on the go.

I also think you're making a bad assumption, that everyone is using their phones in the same capacity that you are. Clothing is a bad analogy as well, considering this assumption. Not only do people prefer different fits from their clothes, but such an analogy would really only extend to the shape of a smartphone and not its capabilities or its application, which obviously varies widely depending upon what you want to use yours for. The fact of the emergence of the portmanteau "phablet" should be justification enough that tablet capabilities are being increasingly viewed by a large amount of users and companies as desirable, and that your view of what tablets should be used for versus what phones should be used for might need less black and white in it.

I have a Galaxy Note Edge, and it's my favorite phone that I've ever had. I've had phones from the Note series since my MacBook pro died, and having such a versatile phone is what's kept me from feeling the need to get another laptop.

It honestly sounds like you're bent out of shape that the larger phones have spiked in popularity and that's driving the market in a direction you don't want it to go. Which is tough, if agree, as they really aren't making smaller ones right now. At least not any notable ones. My SO shares your opinion, and has therefore kept the same phone for almost three years straight now.
