It’s a good question. My colleagues and I have debated about it since the iPhone 6 and 6 Plus introduction.

Right now I’m very happy with the size of the iPhone 6, but there are times when I’d love to have a bigger screen. For example, when reading Instapaper I prefer the larger screen of my iPad. I wonder whether things would be different, if I had an iPhone 6 Plus. 

So far I’m happy with my choice (the best iPhone I’ve ever used). Time will tell, and next year I might make a different decision.
