Agreed; I RTFA in order to learn something about the patterns for broadcasting, reflecting, and cancelling out of these waves. Instead, the images were created by someone who has less of a clue about radio waves than even I do, and they didn't even try to visualize anything even remotely close to reality.

TLDR: Ooh, pretty colors.

Sometimes a person is perfectly fine with buying and using a toaster instead of buying and using a whole oven.

The same goes for tablets; for casual surfing or communications, a slower, smaller tablet is fine for many people. Those who have tasks that require more CPU power will, of course, purchase different tablets more suitable for those types of tasks. But those uses don't' negate the value of cheap, "lightweight" tablets for other users' uses.

In any problem, if you find yourself doing an infinite amount of work, the answer may be obtained by inspection.
