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.
> there’s essentially (literally?) no difference between an iPad and MacBook hardware
Form factor. Touch screen. GPS. Cellular. Circular polarization. These are all literal hardware differences between the iPad and MacBook, and every single one of them makes the iPad suitable for my use case (ForeFlight running on an iPad mounted to the yoke) where a MacBook would not be.
Also, can you give an example of a laptop (or non-Apple tablet) with a circularly polarized LCD? I've never been able to find one, but it's not a spec that's often published…
