BT file transfer, in addition to NFC initiated BT file transfer had already been noted prior to WP8’s official launch by hands on with WP8 devices that had this feature mentioned in the device.
You can share Music/Documents/Pictures via Bluetooth to another Bluetooth (or NFC BT) capable device or use NFC-WiFi direct (P2P without the need for access point) which would be a lot faster.
Either way, it might be a convenient method for some people to transfer information between each other if they’re in relatively close proximity. BT file transfer will be appreciated in various parts of the world, especially where WiFi access or mobile internet access is either not that widely available or too expensive.
So, BT file sharing and Drag and Drop. Nothing to go ranting and raving about, but it may come in handy for the select folks that insisted on this being there.
Cheers Viipottaja for the tip!
