Display
With a 3.5-inch TFT resistive touchscreen, the Asus P550 offers a basic visual experience by today's standards, with the capability to display 65K colors. The screen resolution of 240 x 320 pixels results in a pixel density of approximately 114 ppi, which is quite low, but adequate for the application of the era. Navigation via touchscreen might feel a bit archaic, relying on pressure rather than the feather-light touches modern capacitive screens allow.
