That’s an incredibly inaccurate comparison. Sure if you oversimplify you can draw those similarities, but Metro is vastly different to 1.0.
Gaudy colors is inaccurate. The Win8 screen used there uses bright, pastel colors, but it’s important to note that
users will be able to select a color theme. The tile colors are defined by the apps pinned to the Start screen, just the same as how desktop icons work. 1.0 was limited by the color depth that computers of the time could display; Win8 uses subtle gradients and shades/tints to create a much more pleasant color theme.
As for the window management criticisms, the comparison here is flawed because Metro utilises varying typographic size, negative space and overall better layout – everything has breathing space and is clearly segregated. In 1.0, everything has to be crammed into the tiny screen, all type is displayed at the same size and there’s virtually no empty space, which creates a noisy look and feel.
