Yes. The problem is, there are two screen size for iMac, Macbook Pro, Macbook Air and iPad.

And yet they only have 1 for iPhone. I dont agree with different product line either. But Just 1 more, 1 more larger screen size. There are a world of people who NEEDS to use their both hand anyway. ( As the article points out, those who actually needs to write their languages instead of typing it. )
