What's funny is that Samung's defense is percisely the reason I love Apple. Apple's attention to even the smallest detail is remarkable and is well known in the industry. I don't care if Samsung thinks those things not important. True, there's a certain segment of the market who could care less, but I and many other people do care.
I just hope we don't see a situation where we have too many models with barely a difference between them other than size. This will confuse customers. I remember one of the first things Jobs did was kill off all that were all too similar. Granted we don't have this problem now, just sayin.
Why? There's no need for another layer of confusion. People don't miss what they don't need. Each app handles the files it needs. Let me ask you, when you pick up your iphone or ipad, what is the first thing you think about? I would bet what functionality you want to use, not what file you want to search for an app to open.
