Let me ask again. Apple professed for years, 3.5 inches was the perfect screen size. And the Apple hopeful completely ate it all up and were in complete agreement. So now they believe 4 inches is perfect and that's how they advertise it. So if 4 inches is the perfect size, what about all those years at 3.5 inches?
Couldn't you say any company will claim their latest and greatest product is the best, or perfect? Even if it changes down the line based on market dynamics or whatever.
