Well, I received my replacement unit today, it appears that is the same unit with a new screen, not for sure, but it has the same MAC address as the first unit.
The screen is amazing, much more white than the first, the first units screen was more like my sony reader, more gray than white, this unit looks very much like paper, the contrast is incredible, the black is so dark it looks like sharpie marker on printer paper.
There is almost no ghosting at all anymore, it is so faint that if you are not looking for it you will never see it, it is very easy to read now, no lines between the lines anymore.
I also loaded the new FW and they have made some great changes, glad to see the improvements in wifi conectivity as well as the calibration unit.
Thanks iRex for fixing my unit, it is now much closer to the price I paid for it
Now if we can only get some US newspapers to sign and some way to auto upload RSS feeds via wifi every day then this will be a real contender to standard print and PC reading.
