I haven't seen a better side-by-side comparison of two companies who illustrate the two sides of that coin than Apple and Samsung. You may not always agree with the changes that Apple makes to their devices, but in hindsight everyone can see where they were going. Samsung on the other hand, puts their finger in the air and tries to guess where the market is going in the next year, so that they can beat everyone there.
