I find the 600 Sony case light to be most comfortable with the light positioned just above the middle left-side of the screen rather than top down. In other words, just lift the light a few inches above its resting position and angle the LEDs to the right.

I wish I had purchased the black 600 as there can be quite a bit of glare from the LED's on the silver frame. You have to position the light just far enough left or above so you don't see the LED lights peering back at you.

HarryT: At night the 600 with light looks almost as good as the 505 at its best in daylight. In fact, I use the light in poorer light conditions to compensate for the reduction in clarity from the touch-screen. In artificial light I find the 600's screen to be similar to the 505 fitted with the light-wedge turned off, if that makes sense!
