I would love Wifi to go on my charging stand.
I would love Bluetooth to come on and connect to my JBL speaker.
As of now it seems like it is just an app launcher. Will the app that WPCentral talked about a few weeks ago do these things? (forgot the name, can't find it in search)
Try searching 'NFC' in the Store, there're programs for you to reprogram your NFC tags to launch stuff. Don't know if they'll work with the NFC in the speaker, but I know it definitely cannot turn your Wifi off/on, it's an OS level restriction (I think that's what it's called).
