You people?
I'm not even talking about the user side. I'm focusing on the business reality side. Any manufacturer that only puts out five models is going to be out of business. It's not the way I want it but it is the business reality.
I worked in the cell phone industry. Every manufacturer that only carried five models is out of business. Even Apple had to expand its offerings because they were losing market share and putting themselves at risk.
Five models creates more monopoly power, not less. Things would get so much worse than they are now. We would need to change the entire market place demand structure in order to make 5 models a workable option.
And you don't want people tuning cell phones. That's a recipe for brand damage and goes against the idea that their devices are ready to use for an easy and seamless experience. The customers would revolt.
Again, not my preference, business reality.
