I've had both a Chromebook and most recently and Android tablet with a magnetically attached keyboard, and it's great as a "I don't quite feel like bringing my proper laptop" device crossing over to a tablet, and it fits in my coat pockets.

It's a bit on the heavy side, but have pretty much supplanted my Android tablet. The Chromebook had a similar position, but then I still ended up bringing my (smaller) tablet with me.

For me at least it will never supplant a "proper" laptop because I want a full size keyboard and a much bigger screen, but it's a great complement for travels and meetings etc. or just to bring along in case of emergency.
