da_jane: Let me address the backlight issue as 42 readers of the 60 some who responded on my blog wanted a backlight
What Sony should have done is to include customized LightWedge (or similar) book light (for free!) and nice case (for free!) to fit both reader and the light. It would solve issues with reading in bad light condition. Making backlight built-in, if possible at all, will ruin battery life, imho.
Here is more info on LightWedge system:
(The light can run for 40 hours on four AAA batteries.)
