My favorite door is the Dog Door!

The dog is more life-changing than the iPhone. No more getting up at 600am to let the dogs out, or letting them in and out every 45 minutes during the day. We can sleep all night and not have conversations constantly interrupted by dogs who want to go outside now! Caveat: you need a fenced yard and live in a place where pesky raccoons or Boa Constrictors (Think Florida) won't sneak in.
