Does the Samsung Galaxy Note (and Note 2) have a special screen?

Does the Samsung Galaxy Note (and Note 2) have a special screen that makes it usable with a stylus?

Its magnetic or something like that. Not entirely sure how it works but it's something to do with magnets.

EMR® (Electro-Magnetic Resonance) Technology
The De Facto Standard for Pen Tablet Devices is Realized using EMR® Technology

The characteristic appearance of Wacom's pen tablet devices is of a slim and lightweight electronic pen that has no need of an obstructive cord or battery, along with a completely non-contact-type sensor board that makes possible a wide diversity of flexible built-in processes. These devices make adept use of Wacom's originally developed EMR (Electo-Magnetic Resonance) Technology.
Electromagnetic Induction-type Pen Tablet Devices Other than Those using EMR® Technology

Most non-contact-type pen tablet devices apart from those employing EMR® Technology require some kind of internal power source to generate the signal on the pen-side circuit that enables the pen's coordinates on the tablet to be detected. These include devices powered by electricity supplied via a cord and others equipped with internal batteries. However, cords can be bothersome to use, and there is always a worry that batteries may run down at a crucial time. Moreover, the presence of cords or batteries makes it harder to optimize the pen's size, weight, shape and balance. Accordingly, these devices cannot be said to provide operational freedom without constraint.
The Principles of EMR® Technology

Despite being non-contact systems, pen-input devices utilizing EMR® Technology do not require any cable or built-in battery-based power supply at all. This is because the tablet surface incorporates a sensor board that detects the pen's movement. Weak energy is induced in the pen's resonant circuit by a magnetic field generated by the sensor board surface. The pen's resonant circuit then makes use of this energy to return a magnetic signal to the sensor board surface.

By repeating this movement, the board detects information on the pen's coordinate position and angle, as well as on its general operating condition including speed and writing pressure, etc. A sensor unit is equipped at the side of the sensor board to switch the magnetic field on and off and to receive signals at high speed and detect various kinds of information. In principle, all Wacom's tablet devices are composed of this kind of sensor unit and electronic pen. In addition, the sensor unit itself consists of a sensor board and a control board.

Sensor Board

The sensor board consists of a thin sheet manufactured from glass epoxy resin or from a polyimide and PET formed film in which a large number of overlapping loop [antenna] coils are arranged in a matrix in the x and y axis directions. On the rear side of the sensor board is a shield board installed to block out noise from other components such as the motherboard and nearby circuits. The thickness of the entire sensor board that combines these elements is only 0.6mm. Although there are slight differences according to the size of the sensor surface, in the case of a 2.2" (diagonal) sensor, the thickness of the board is only 0.25mm.
Control Board

The control board discharges alternating current to selected loop coils from among the array installed in the sensor board. This excites the coils, causing them to generate magnetic fields. When the pen passes through these magnetic fields, it picks up and stores energy in its resonant circuit.

The control board first detects the pen's rough location by scanning the loop coils on the sensor board. After that, the control board scans multiple loop coils in the vicinity of the pen, and uses the information to calculate the pen's coordinate value precisely.

That cat looks poorly

That cat looks poorly
I agree, looks half dead.

I think "yes", sufficed...

You phillistines
'Tis true, unfortunately :(.

Saying that, the N2 screen is pretty cool, air-view still kinda amazes me :p.

My work just gave me a Note 2 so i'm happy. Been using it for the past week and it's easily one of the best phones i used. Already rooted and installed wanamlite rom. Plus i got the 4G version so i'm keeping this for a while now.

Only dilema at the moment is what to do with my dual sim phone. I really wish the Note 2 was dual sim.
