For the following reasons:
You don't have to fake an orgasm
You don't have to lie there wishing it would be over
You don't have to give it a blow job or a hand job
You don't have to say "Oooh, you were wonderful! /The earth moved/ What was your name again?" Or whatever.
You don't have to check up on its whereabouts (it's in my knicker drawer) or worry that it might be having sex with an OW.
It won't have football on TV day and night.
And the way technology is going, vibrators will soon be able to talk to us, buy drinks AND do the housework.
