Yeah, I'm basically email/documents/web as well (when not at home) and I've occasionally given the iPad Pro with pencil and external keyboard a shot for working on a short trip. I admit I probably haven't given myself enough time with the various multitasking features to use them reflexively but I've just never been able to really make it work for me. I can in a pinch on a short trip where I'm mostly just doing some browsing and maybe taking some notes but I'm more inclined to just bring a laptop and ditch the iPad entirely. In fact, I don't really use my iPad at home much and I'm not sure I'll replace my current one which is out of or going out of support.
