It's the way capacitive screens work versus the way an active digitizer works. I won't go into great detail behind the technology but you can search the technical information on it if you want. Basically capacitive touch screens were designed to be used by your fingers. The touch screen senses the difference in displacement by your finger touching the screen areas because the sensors were designed to react to anything that is more conductive than air. Since the human body is a good conductor you can use your finger to touch the screen and control things. This allows you to use multiple finger gestures such as moving your index finger and thumb apart to simulate zooming in or moving them together to simulate zooming out. But this design is also terrible for drawing because it has some flaws. When you rest your arm on the capacitive screen it will detect your arm because it is conductive along with the stylus pen you're trying to draw with. This makes it very difficult to draw on the screen because you cannot touch any part of the screen with your body when using the capacitive stylus pen. What makes it worse is that the stylus pen tip has to be wide enough for it to be detected by the screen making it impossible to draw fine lines and detail.
Because of its design, capacitive screens cannot accommodate for pin point accuracy and pressure sensitivity. Unless you're just doing simple drawings and illustrations like a simple caricature drawing or simple cartoons it's just simply a terrible technology for fine detailed drawing. Without any accuracy and pressure sensing you can't use say a G-style pen to make thicker and thinner lines with pressure such as you would be able to on something like an active digitizer or a Wacom tablet pen. An active digitizer pen is superior for handwritten documents, has nearly pinpoint accuracy, and will not have the pen/arm problem on the screen because only the stylus pen's tip interacts with the screen. So this makes it possible for you to rest your arm on an active digitizer screen without confusing the tablet by telling it what you want to do as in the case of a capacitive touch screen tablet.
There is however a method to combine both of these technology together called "dual digitizer" meaning the screen uses both capacitive touch and an active digitizer. Basically you can use your fingers on the screen like a normal touch tablet and when you write with the active digitizer it shuts off the capacitive sensors so you don't get the arm problem like on the purely capacitive solutions. Last I checked both Lenovo and Fujitsu offered this as an option but it is definitely NOT
Also don't forget about the Microsoft Surface Pro as an option. It seems to use a PLS screen and an active digitizer so the color gamut will probably be not wide enough if you need perfect color. See Jonathan Case's review
(he does some of the DC comics).
