It's been along time since I've been on these forums. Started when I got my Surface RT and continued up to the time I got my Surface 3. I've loved my Surface 3, and if I didn't have so many charging issues wouldn't need to think about upgrading now. But it won't take a charge anymore, so I've gotta move on. I'm going back and forth between a Surface Pro (m3) or a Surface Book. I think I might like the slightly larger size of the Surface Book. Anyone who has used both have preferences? Mostly, my device is a word processor, I write at least one sermon and one bible study each week. Then I use the device to have access to my written presentation as I present. Surface RT and Surface 3 have served me very well, but do I want the bigger screen offered by Surface Book, or would I be satisfied with a Surface Pro?
