I am designing a handheld product that requires a GUI. Using character LCD modules and buttons seems crude and disjointed for today's consumer electronics devices. I am impressed with touchscreen LCD GUI modules offered by companies like Amulet technologies. They provide the user a rich interface with touchscreen control. However they are very expensive.

I would like to find lower-cost embedded GUI packages or at the very least low-cost graphic monochrome touchscreen LCD modules (less than 4 inches in size). I would appreciate any advice.
