In ambient light the contrast is worse on the Daylight than the RM2 - the screen background is quite significantly darker.
However, the Daylight has a backlight which increases the contrast enormously. And it’s usable in the dark which the RM2 is not. The much faster refresh rate also gives it a more fluid feel.
What I didn’t anticipate is the difference the screen makes in how I use and perceive them:
As the RM2 is so simple and static it feels more like a notebook or book reader that happens to be battery powered, whereas the Daylight is definitely a gadget.
I’m more likely to use the RM2 to take notes or do some thinking and the Daylight as something to tinker with.
