Honestly to the extent that's true, I think the 16:10 android tablet is the clear winner as video content matches one device much better than another. Landscape web browsing is probably best done in squarer ratios, but I'm not sure that's universally agreed (desktop computers, for example, spend their browsing existance at 16:9).

Again, this seems like splitting hairs to me -- trying to come up with something that makes the mini "special" and not just another 7" tablet. Why can't it be just another 7" tablet?
