Interesting display. Depending on where the GUI images/sounds are stored, it can be either a boon or a bane

Usually, a TFT screen needs a huge amount of data per image which has to be displayed. This is usually a luxury on low end processors. Assuming the graphics are stored on the display, the display would be suitable for static screens with small areas of changing data. There is not much detail on how they store the images/sound files; others usually use a SD card memory on the display to store such data.
