Well people who wanna buy thin cases don't wanna add any bulk and keep the iPhone's orignal look while having scratch protection at the same time.
You don't have to be a rocket scientist to figure out that when you buy a 0.35mm thick case it won't protect your phone if you drop it!
By the way TechDude, I still can't find that Desmay case you were talking about!
Are they any good ?
