Netfilx is a web based thing, were you can only use it through their web page, ie its something like facebook. It inst really an application. It only really becomes an applications on the Iphone of Whatnot is because it flash heavy requirement and i assume the browser built in cannot fully support it. Meanwhile an application like Microsoft Office cannot be installed or let say photo shop since those are 3rd party applications.
As far as the chrome goes all software and everything else is backed up online and all applications are used online through the browser like netflix.
