Personally I liked 8.

I thought a tablet + bluetooth mouse + bluetooth keyboard + cheap plastic clip - trackpad made a great laptop but I think I was the only one if you don't count Balmer and Sinofsky.

I don't know if synaptics had some patent they used to force everybody in the industry to make laptops with trackpads [1] or if the flight attendant's union got too confused about whether you can stow a 2-in-1 in the pocket in front of your seat, but it just didn't fly with most people.

[1] in cases where you couldn't use the mouse fall back to tablet mode
