Over 6000 is quite exceptional. This generation of iPhones are considerably more powerful than my wife's 2 year old Asus with the Core i5 CPU.
On another note, it's 750p. The screen is still quite sharp. Is there a difference between the 750p and 1080p screen (326ppi vs 401ppi)? Sure, but it's slightly above negligible. Stop your complaining, no one forces you to buy Apple.
