It's what we have been waiting for, the transparent toaster. A company called Inventables has designed the concept that is still a few years away from showing up on the shelves of Wal-Mart.
The concept is simple, the glass heats up and browns the bread into toast. I can see a number of positives for this devise, the main one being you are no longer dependent on your nose to determine if the toast is done. Usually, when you can smell your toast it is too late. Now a quick glance up from the newspaper will allow you to gauge the time left before you have the perfect piece or pieces of toast.
It is indeed what the world has been waiting for.
