This morning, Nokia Conversations posted their final Nokia N8 video overview. Chris Bennetts demonstrated the N8's music player, accessing context-sensitive menus by long pressing an item, as well as the new coverflow music interface. Also shown was the N8's HDMI output, which was very impressive. However, what stood out to me while watching that part was Bennetts' emphasis on Bluetooth control...
With older versions of Symbian, drivers were available for Bluetooth keyboards and game controllers. But, as far as I can recall, Bluetooth pointing devices were never supported through the OS. Look at this:
I'm currently awaiting some confirmations and details, so I'll update this post if I get anything new.
EDIT: Symbian^3 does indeed support Bluetooth mice. You can check out the Bluetooth HID drivers (and other stuff?) here on the Symbian developer website. Thanks to Brendan in the comments for pointing this out!
EDIT 2: I can now confirm that the N8 does natively support Bluetooth mice.
