It seems to me that the update process is slightly more jarring on OS X than it is on Windows (though I haven't used the Windows version so I am just assuming).

It seems to me that the update process is slightly more jarring on OS X than it is on Windows (though I haven't used the Windows version so I am just assuming). When I finish using Chrome on OS X I will close the last tab with Cmd + W, so Chrome is still open and therefore it won't be able to install the update next time I open a tab. On Windows I would close the last tab and the application exits completely – though it might take slightly longer to open Chrome each time, I will never really have to manually restart Chrome to get the update installed.
