Why?#1, You could be using the extra space for more things.
You can count on me to be eating cold tofurkey pizza (vegan)! I did an experiment on myself where I basically ate the cold pizza first because I didn't want to wait 15 whole minutes for the conventional oven to bake it for me. And I never like to use the microwave, too. So, I ate it cold. It was delicious! Or maybe I was just too hungry... I don't know. I ate a few slices then put the rest into the oven (it's a small one). It didn't taste as good as cold and I figured I'm never baking tofurkey pizza again. This just gives me even more reason to not get an oven.
No more ovens!
