Woosh - stop trying to justify your invalid point. I just bought a house and a new car in 2012, and have all the credit I need. Would I give up 10 or 20 points for 2 years if I can get a new phone for half price? Yeah, I would, because I don't need credit for anything else. Plus, my score would still be "Excellent" even after 2 hard pulls.
So, since I have an "Excellent" credit score (780 average across the bureaus), you are grouping me into the category where you assume my time is more important than my money. Wrong. "They can buy an iPhone because their time is worth more." - no, I prefer to pay as less money as possible on every purchase I make, regardless of my credit score. Plus, it wouldn't take 10 hours to execute the OP's strategy.
Just get out.
