Earlier quoted context omitted.
A 2880x1880 screen, with top of the line CPU with highest build quality at $2199 IS mind-blowing. Those screens don't come cheap.
We need to remember that it's the nature of technology to continuously improve. We tend to take it for granted, but that is because continuous improvement has been that reliable. 2 MP 15" displays were available in 2002 and were a $2000-laptop technology by 2006 if not earlier. It is not surprising that 5 MP 15" displays are $2000-laptop technology six years later.

So I'm having issues with the statement that technology continuously improves. In many areas that's just not true.
