But what is crucial is that Chrome ignores some of the Metro design ideas that Microsoft has been pushing.
Microsoft insists that if you right-click or press "Windows key + Z," there should be an app bar that pops up at the bottom of the screen.
Google is using a traditional menu bar in the top right corner that you can click for settings and app changes. There's also standard tabbed browsing.
Like IE10, Chrome includes Flash Player built into the browser for viewing all kinds of Flash content. But again Google stuffs up Microsoft's cunning plan by ignoring an approved list of sites and Flash content. Chrome plays the lot.
What might make Chrome more popular on Metro is that it stands in a half way house between the new approach that Windows 8 is driving people towards and the older methods that people are familiar with. This could make it popular in the short term while people work their way around Metro.
