A good way to think about it is via Occam's Razor: Which states that "Multiplicity should not be posited without necessity" Thus the pioneering products in any new segment are simple, however as time passes new "necessities" emerge, which means the product "must" be modified to fit those needs. This also assumes a well regulated market with rational buyers (no fanboi's). Note that this does not means that Simplicity should always be favored or The simplest solution is usually the correct answer, even if there is a single legitimate need which a simple solution cannot address, then the solution must be made complex to address that need effectively. Evolution of Personal Computer or any non monopoly product is a good example.
