We didn't get rid of it for health or radiation concerns (though I have heard of DR. recommending people with cancer and other chronic conditions move their microwave out of the living space). We had a roommate years ago who took it upon leaving and never bothered to replace it.
It pisses off some of our guests when they come here expecting one, but I can't say I've ever had an 'Ugggh! I wish I had a microwave!!' moment. However, I've come across some cool things over the years that IF I DID have a microwave, I would use it for this....
Potato Chips
Chocolate Cake (made from scratch and baked in a mug)
Tortilla Bowls
Blow Up Ivory Soap
Grape Lightning Balls
