My biggest complaint with the kindle (post beige / side buttons era) is the black plastic. If i read in the sun for 20-30 minutes the device begins to get very hot. After 40 minutes the heat starts to cause performance and display problems. Using a towel or newspaper helps but it screws with the mechanics of holding the device and turning pages.
