With Windows 8, Microsoft introduces the Metro Apps which run in a sandbox environment, and therefore should be more secure. I would be interested to know if this higher security that the metro apps bring to the Windows OS also apply to the Chrome Browser, that is I want to know if there is any advantage from a security perspective to run Google Chrome in Metro Mode over the Desktop Mode ?
Wikipedia: To ensure stability and security, apps run within a sandboxed environment, and require permissions to access certain functionality, such as accessing the Internet or a camera. The sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In this sense, sandboxes are a specific example of virtualization.
Windows 8 introduces a new security sandbox, called AppContainer, that offers more fine-grained security permissions and which blocks Write and Read Access to most of the system. AppContainer is a new isolation method applied to Metro apps, which by default prevents them from reading and writing to most of the Operating System, with the exception of the app’s own AppData folder.
