1GB iPod nano screen dimmer than the 2/4GB versions?

There's not a whole lot to say about the 1GB iPod nano that hasn't already been said about the 2 and 4GB versions of the same iconic player, but in iLounge's official review of the device they did note that the screen isn't backlit nearly as well as its older siblings. We have no idea if this has something to do with a new screen components supplier in late-model nanos or if this is something specific to the 1GB version, but if you should happen to have a some nanos of various sizes lying around, let us know why don't you?
