John Siracusa is certainly aware of Windows, at least visually. The only reason for you to suggest pointing out any little thing that's not "Apple-original" is out of some sort of pointless OS defensiveness. Aero Glass was a simple blurred translucency, while the translucency in Yosemite is a more complex filter and has two content modes, behind-window and within-window. But I don't see what comparing the two accomplishes, honestly.
