Excellent, that would become my 3rd kindle if it delivers on retaining clarity :-) Thankfully most of my favorite authors don't use DRM to make that inconvenient (I currently use both my kindle's and use the sync to page between devices a lot ... which won't work when I strip the DRM).

My past experience with the front light on my Casio fx-9860 GII and watch (Illumuminator, like timex's indiglo) is pretty good and uniform (altough very blue). The film used on my watch has a bit greater clarity than my calc, so I guess there are some cost considerations in having layers with excellent optical properties.

The front light on Sony PRS-700 was apparently a disaster for most users, but lower-contrast and a touch-layer in addition to the side-lights might have added to the fuzzy display.
