The design of everyday things is such a wonderful book. When I first read a review about it, it said “you will never be able to see a door in the same way” or something like that. I thought it was an exaggeration. It’s not. It will change the way to think about everyday objects’ design and usability. Today I was listening some music. The headphones cable hit a little bottle of some medicine I am taking for allergies. Of course the bottle rolled down the desktop to fall onto the ground. Thankfully it didn’t break. Now, what is the reason of having round, cylindrical bottles ? None I can think of (apart some economical I don’t know about not being a bottle expert). Please, give me square bottles everyday. Every detail matters.
