I'm 28 (just outside your demographic) but I have an iPad Pro 12.9" as my main driver and a 27-inch iMac at home. I am a software engineer by trade but I don't have time to do that outside of work so that's not a concern. I carry the iPad with me throughout my house and use it for just about everything. I also take it with me to the high school classroom where I volunteer teach computer science. All of their assignments are online so it's super easy to access them via the iPad. Could I replace my iPad with a MacBook Pro? Sure. But the iPad is smaller, has touch, and does everything I need. Not sure if this was the answer you're looking for but I figured I'd chime in.
