Of course you should try it out... but its not as though people have stopped buying phones of this size.
Each to their own, I have my 27" iMac, an iPad (full sized) and my iPhone 5, they suit me perfectly, each for specific purposes. I have no need for a Phablet, but I know many who want and have that as their only such tech. No laptops or desktops at all.
I've never boohooed them.
