I am at 50% brightness atm.
Same here. I usually have 6 of the MBA's 16 brightness indicator increments lighted, which is 37.5 percent of maximum brightness.37.5%
You're so precious
Right now, I have it on full blast. Sitting in the sun on a sunny south florida balcony over looking the gulf.
Can you see the screen well in the sunlight? I always have trouble, especially with videos.
I keep it at 50%. I don't see a huge difference between bars at higher levels.. Sometimes gone as low as 1 bar..
Of course there are 1/4 increments too (by using shift+option F1 or F2 ...)
