Nathan Brookwood:

Android and iOS tablets do a yeoman’s job when it comes to consuming content, but lack the software tools and hardware features needed to create content. Windows-based tablets, which have been around since 2002, have always included the features needed for content creation, but lacked the easy to use interfaces needed for content consumption. The Metro User Interface in Windows 8 supplies these missing elements, and thus positions Win 8-based tablets as the only ones suitable for those who want to both create and consume content on a single device.

Bullshit.
