The Asus ZenBook Pro 15 is a strong performer with a beautiful design, but while the ScreenPad is innovative, it’s not fully baked and contributes to short battery life. The ZenBook Pro 15 is opulent. The laptop, ($2,299 as tested, $1,799 to start) is a lavish machine, both on the outside with its good looks and on the inside with its Intel Core i9 CPU. It’s so extra that it’s got a second display under its touchpad. But that ScreenPad, while interesting, could use more time in the oven, and the laptop’s poor battery life means it’s not as portable as it should be.
