Whether or not you think a logo should literally depict a name, I think her point was that the logo was originally intended to be a literal window: the Windows 1.0 logo was a picture of on-screen desktop windows, the 1989 version was a physical window, but in 3.1 they hopped the rails to a wavy thing that got steadily more flag-like.

This new version is a step back to the roots of the original design. It's clean, it's clear, and I like it.
