The garbage disposal is indeed one handy dandy item, but if it breaks, I can scrape plates into the garbage. That only takes a few seconds!
If my dishwasher breaks, I have to wash all dishes by hand, which takes anywhere from 30 minutes to an hour depending on what I have cooked and/or what has piled up during the day. <img src="/images/graemlins/crazy.gif" alt="" />
Also, the dishwasher assures my dishes are being sanitized. If I want to do that by handwashing, I'll need to do a Clorox soak and then ultra-hot rinse. Sooooo don't want to take that time!
