The battery on their arm devices are insane. I can disconnect my laptop at 100% without shutting it down. Go home. Sleep. And then work another 8h without the battery dying on me.
It's very impressive. I can't think of other laptops that have comparable battery life/performance combo as that macbook pro.
My previous (work) dell laptop barely made 4h ( more like 3 ) and was in the same price range. While I'm not an apple fanboy at all, and there are basis things it just cant do natively ( keyboard window management needs an external app?? ), their macbooks are absolutely the best laptops I've ever worked with.
