IMO, it's reasonable to complain about the iPhone's size because you only get two options, 3.5" and 4". It makes sense for Apple to produce a larger phone for people that want to stay in the Apple ecosystem and aren't happy with the current offerings. But Apple probably knows better than me
So it's reasonable to complain about the Galaxy Note size because you only get two options, 5.5" and 10". It makes sense for Samsung to produce a smaller galaxy note for people who want the s-pen and s-voice and aren't happy with the current offering. But Samsung probably know better than me.
