Notes:

  • Screen size (physical) measured in millimetres (mm). Width then height.
  • Screen size (resolution) measured in pixels. Width then height.
  • Black and white (b+w) screen can show several grey scales or shades simultaneously. The Series 7 can show several colours simultaneously. That said, some applications do not use all these shades or colours for power conservation purposes.
  • The Series 7 can show 256 colours simultaneously. A palette of 4096 colours is available, but only 256 used at any moment.
  • The 3c (b) is the Series 3c backlit model, first introduced in North America.
  • The 3a (512) is an early generation Series 3a with 512KB RAM.
