of course, you are both comparing the difference to... zero?!

(you should compare the price difference to an equivalent laptop (however defined) if you're talking "marginal")

I'm not comparing the difference to zero. Note my convoluted phrasing which I wrote specifically to forestall your objection:

> you've made a marginal $55,000 a year since 2009 which you would not have made with any cheaper laptop?

Of course I don't think he actually has, and that he would have gained pretty much whatever he has gained with a much-cheaper-than-$3k-laptop.
