Using a tablet as a laptop, it's a just in case thing

While some folks make an effort to leave the laptop at home and just use the iPad or Android tablet as a full-time system, that's not my approach. That smacks more of an attempt to make it work so the load in the gear bag is lighter. There's nothing wrong with that, but it's not for me. I reserve my use of a tablet as a laptop replacement for those times when I leave the laptop at home because I don't anticipate needing one.
A tablet is easy to throw into the gear bag with a keyboard, so that's what I do. That turns the unexpected work session with the tablet into an extra benefit, not a forced session that may not be as good as using a real laptop. I don't do to prove I can do it, I am able to salvage an unexpected opportunity to get some real work done without compromise. It's a "just in case" thing that saves the day.
The tablet has revolutionized my free time with the many things it can do no matter where I happen to be. It is comfortable to use for long periods in the hand, and battery life is so good I never even think about it. I just throw it in the bag and use it as I desire. Sometimes the muse hits no matter where I am, and having a keyboard along is a very good thing. I don't use my tablet as a laptop replacement, but it's nice to be able to do that at a moment's notice.
If I was setting out to get a work system, a laptop would definitely be what I looked for. Those who insist that it makes more sense to get a cheap laptop than buying both a tablet and a keyboard to get work work are correct. But the truth is I already have a tablet for other reasons (several in fact), and several laptops too, so using it with a keyboard is not an either/or situation. It's a just in case thing.
