BrowserSync is pretty good and supports multiple devices and lot more. There's a grunt task.

I would love to see this as well; the new HTML injections that BrowserSync almost has ready are going to be awesome :)

I would love to see this as well. It mirrors the yeoman/generator-webapp change as well (refs issue 400 there).
