yeahh same here...if i don't have my charger (like today i forgot to bring it to a meeting) i put it on one box and gives me like close to 6 hours of battery which is hard to believe but its true. And its really bright enough unless theres sunlight giving you a glare.
Yes and if you go all the way dim the screen is black, which I love this feature. Especially when listening to music etc.... Why wear the screen out when ya don't have to? I wish my iMac would do that! 🙂
