I believe they used Pixel Qi displays, which were transreflective. I love transreflective displays due to their ability to use ambient light to save power but since the colors don't 'pop' with these and the side-lighting creates uneven lighting, they never seem to get traction. My Sharp Zaurus SL5500 and Garmin Vivosmart HR have these displays and I love the battery life that accompanies them. Edit: Additionally, for a while Pixel Qi made their ~10" (1024x600) display available as a retrofit for netbooks, probably around 2012 or so if I recall.
