This is an awesome article, Julia! I can't believe how many poorly designed items we just accept as standard. In today's world where we innovate so quickly, it is mind-blowing to think about how many basic things have stayed the same. There are a few of these that would be difficult to change and have high switching costs - like the keyboard or US currency. However, you would think things like kitchen appliances and tv remotes would be easy to change!
All this being said, I wonder how people would react if all the sudden Heinz changed the shape of their bottles. There is definitely a nostalgia aspect to some of these poor designs. People associate Heinz with a certain type of bottle and I can remember people saying "tap the 57" for as long as I've used ketchup.
