Google confirmed to Mashable that it is developing a Metro version of Chrome for Windows 8 users.



From ArsTechnica:

Plain Metro applications on Windows 8 are tightly restricted, with limited access to the operating system's features. Desktop applications are essentially unrestricted. Browsers are a special-cased hybrid between the two: Microsoft allows browsers to offer Metro front-ends without subjecting them to the Metro restrictions. These Metro browsers have dual front-ends: they run on both the desktop and within the Metro environment.

The Metro front-end will naturally be touch-friendly. Google says it will also work to make the desktop front-end touch-friendly too.
