Tote-a-Tot

Parents know that traveling with kids can be a huge hassle: you've gotta make sure all their various toys and accessories are packed and ready to go, you've gotta carry a diaper bag and a carseat along with your regular luggage, etc. The Tote-a-Tot aims to make that simpler by allowing you to securely attach a carseat and diaper bag directly to your rolling luggage, and even stick your kid in the seat to make it simple to keep everything and everyone in one place. (Just make sure this is your carry-on, not your checked luggage!) $24.95 USD. (Thanks, Doug!)
