The N9 runs MeeGo, which as you likely know by now is the combination
of Nokia's Maemo and Intel Moblin. MeeGo in smartphone form has
something we've been waiting patiently for. The N9's industrial design
looks nothing short of stunning, though all of the photos of the device
so far appear to be renders and not actually physical hardware.
What's unique about the N9 is that the front of the device is
buttonless, virtually everything is accomplished by tapping on the
capacitive touchscreen, including unlocking the device. There's still
volume, power, and camera buttons however.
