Well if all the other advantages (well documented herabouts
) of the display haven't swayed you thus far, I'd suggest that you find a Sony and have a look at e-ink for yourself, netriones. Unfortunately, the reality of e-ink just doesn't translate well to pictures, you really
do have to see it to grasp it.
If you see it with your own eyes, and still think the LCD will do for what you need, then by all means go with the LCD.
