I don't think this is fair. Of the uses listed:

iPads are better for watching shows on a stationary bike, since they fit on the bike

iPads are better for reading manga, since you can hold them vertically

and iPads are clearly better for drawing--you can't draw on a laptop.

There are some hybrid laptops that do these things, but they're bad at them. Especially drawing, I've used enough HP convertibles with "stylus support" over the years to know that.
