A month ago I bought a spare 48GX. As it is new, it has black screen. Then I posted something like "the new screen is slightly better, not much better...".
Well, after four weeks of testing, I have decided to use the new black screen unit, and keep my old blue unit in home as a backup...
Now, when I look to the old blue one, I can see it clearly: the new screen is definitly better.
