Taking an already existing idea and building onto it is great. Just take a look at the world’s most valuable tech company, Apple. Apple has been lagging behind in terms of groundbreaking innovation in recent years (despite their wild claims repeated 100x during their keynotes). Yet, their devices are still selling well enough to keep them atop that list. Why buy Apple’s products when you can just as easily spend your money on something that’s actually fresh and new? For many of us, the answer is simple: Apple’s products are designed and manufactured to such a high level of reliability that we would rather be a few months/years late to a technology than have it now and have it break in a couple of days. Apple knows this and they are not afraid to keep taking existing ideas, perfecting it, and spice it up with a cool minimalistic, Apple design.
