Huh?
Samsung makes a 7" tablet, which is aimed at those who like to hold their device with one hand.
The 11"+ screen is perfect for those who have been waiting for a device which can display full-size PDFs and can serve to read full size magazines, such as those available on Zinio, or directly from publishers.
The 10" or 9.7" screens are neither small enough to be truly portable, nor large enough to be useful for 8.5"x11" media, which is the vast majority of PDFs and publications out there. 10" screens are cheaper, and that's about it.
I wish Apple had done this, but it is Samsung, so Samsung will get my $$$.
Cheers.
