I just got back from looking at a Galaxy Note 3 (thinking form upgrading from by S2).
Now I'm not sure - will probably just go buy a Nexus.
I can't think of a single valid reason for this level of functionality to be available in a device that's sold commercially. I've never heard of any enterprise management tools that can use such functions, and their undisclosed existance is a real worry.
The biggest laugh about this is that Samsung Australia is currently trying to get the Samsung Galaxy Note 10.1, Galaxy Note 2 and S3 onto the Australian Government Endorsed Product List (http://www.asd.gov.au/infosec/epl/index.php ) - I don't like their chances now.
