Given the wide aspect ratio of the 27" monitor, I expected to read the PDF in one window while typing my thoughts about it in the browser. From Google Chrome, I opened the PDF document and was immediately zapped into the Metro interface's "Reader" app. My browser was gone. Although the screen is easily wide enough to display two pages simultaneously, the software elected to show just one page at a time, surrounded by massive black bars (see screen capture below).
Instead of looking at a text entry box and the PDF simultaneously I would have to go back and forth between screens, trying to remember what was on each. I tried the same series of steps in Microsoft Internet Explorer and the result was the same.
Now I understand why Jakob Nielsen calls this "Microsoft Window".
