I love the iPad for media consumption and battery life. I like the productivity of the Air. I am trying to see if I can replace my iPad and MacBook Air with a single device. Just wondering if the new Surface 3 tablet offers the closest solution to this problem? Does the Surface 3 wake up instantaneously like the iPad does at the push of a button even after many days or does the Windows OS go into some sort of deep sleep after a certain time? Will the battery life on the Surface 3 be comparable to an iPad?
