The problem is that Koreans improve on inventions but they do not invent (speaking about consumer electronics and user experience etc).
That's the problem with them...they are "soulless" without and identity. They have yet to change their culture to really make a difference.
Do not take me wrong. Their products are great, they work their asses to be the best...but...They are ashamed of being an asian company and they are ashamed of going with their unique style. Hence they copy others and improve their products.
It's the same identity problem they have with Kia & Hyundai on a luxury cars segment (see hyundai genesis and k9 vs BMW,Lexus,Mercedes blah blah).
And it's the same when it comes to comparing cultures with Japanese. Yes Japan has a lot of unique things that are seen badass in eyes of western audience like samurais,ninjas, katana and a concept of honor (seppuku).
But koreans fail at promoting their stuff...they have the easiest most scientific alphabet out there which you can learn in 15 minutes, their admirals were one of the best in the world and their culture defended themselves against superpowers for 5000 years and survived.
They outplayed everyone in the world when it comes to building the largest, heaviest and most complex ships. The japanese, chinese constantly loses and even they build their ships in Korean shipyards. Most of the tallest and complex projects were built by korean heavy industries.
Ad promoting the korean culture, and achievments by samsung heavy industries and comparing them with a S6 Edge would be unique and an epic win.
What you just described is exactly what Apple do.
They don't invent things, they take a type of product that's already on sale, and improve upon it.
Note: Humans have been doing this since one caveman spotted the wheel another caveman just invented.
Apple did not invent the home computer, the MP3 player, the Laptop, the Mobile phone, the Tablet, the TV playback box, the Smart watch.
Let me put it to you this way..........
You make product A: your way, you were early to market let's say.
Another company comes along, tweaks your design, perhaps improves upon it in some way, and the public like it, and this company sells lots.
YOU...... What do you do? Ignore this as a company, or take onboard the changes the other company made, add/incorporate some of these things into your next product, as it's what's selling and what consumers are buying.
I do worry how so many here are two faced. They moan at a company that is doing exactly what they would do in the same situation.
I make lemon lollies.
Another company starts making strawberry ones, and wow the public love them, in fact they like them even better than my lemon ones.
And sensible person, seeing what the public like would also offer Strawberry lollies to capture some of this market.
People here seem to think, nooooooo You should not make strawberry as that would be copying, make a lime one instead, ignore that fact, as a company strawberry is selling.
) won't convert most from Apple... If you want the real deal, you get the real deal, and not some second rate rubbish with that TouchWiz crap (though it's been MASSIVELY improved).
