yes, it has been crystal clear for me in the sun. i tested this early on as it was important to me. I've got the Sports in gray, and am using the yellow text. perfect in bright light.
Well, there's 'in sunlight' (outdoors) and 'in direct sunlight' (sunlight directly on the screen). I know I can't read my iPhone or AW in the latter case.
Yep, I'm at default brightness and tried using it intentionally in direct sunlight. The screen definitely doesn't look pretty (You can easily see the air gap in direct sunlight) but there is easily enough contrast to use it just fine.
