Colour GLCD for calculator project
Wondering if anyone has experience interfacing one of the many higher resolution colour GLCD's now available? I am looking at replacing the black and white 128x64 GLCD I've been using with a colour one. An electronics magazine I bought the other day had an article on interfacing this 3.5 inch GLCD to an Arduino.

It is a 480x320 colour GLCD with an SD card holder and uses SPI to communicate with the microcontroller. My main concern is that the relatively high resolution could result in a slow refresh rate, especially as it uses SPI. Here is a 4 inch 480x320 colour GLCD with an 8-bit parallel interface, which is faster but uses more microcontroller pins.
