I find it amazing that it only took 10 years since the invention (well, it was more a concept because it didn't work at all) of the toaster 1909 for the modern and highly functioning toaster to be put on the market 1919 (which is an awesome year :) ) I believe the toaster is a truly unique invention because not much has been changed with it since 1919. Sure there have been minor changes but the thing itself hasn't changed. This is very uncommon as almost every invention changes to fit the modern era. Its a truly amazing piece of technology.
