It's amazing how many threads I have seen with the basic premise that "marketing makes them do it". Marketing can not turn a bad device into a good one, though way to many marketing teams have tried. Good marketing understand the needs in the market place, then tells a story about how the brand meets those needs. It creates a promise for their customers. If the brand cannot live up to the promise, the brand will fail. It is that simple. The fact that Samsung continues to grow its share demonstrates that their devices are meeting a large market need. Not all needs, to be sure, but clearly a large one.
A great case study of great marketing vs. bad product: New Coke. That product had a marketing budget behind it that was unrivaled, and marketing teams that are widely recognized as among the best period. No amount of marketing was able to save the product. They brought the original back and killed the new.
Every device, and I mean every device, is a balance. Everybody will put different weights on different parts of the experience, and our perception will be shaped by the overall experience. Folks that are biased towards speed specs and light weight OS will experience the Note differently than those with a bias towards a rich feature set. Samsung tells a feature story in their marketing, not a spec story. In fact, so much so, that Note die hards have complained about the lack of spec advancement from the S7. Samsung made a choice, one they believe will serve their targeted customers the best. Sales will determine if the Note 7 is a success, and repeat sales will let you know if Samsung continually delivers on customer needs.
I chose the Note 7, not becuase of marketing, but becuase I like the features it has. The Note 7 story does resonate with me, and so far, the Note has paid off its promises to me. I am very happy. I love the way it looks and feels in my hands, and I love the things I can do with the phone. If there are small hiccups on scrolling, I personlly can live with that.
Could Samsung devices be smoother? Probably. Could they do a better job coding? Probably. Is it what the MARKET is demanding? Doesn't seem so.
