In other words, if you had set aside the $1200 for the low-end 13" MBP and invested it in AAPL, the money you would have earned could upgrade you to a 17" model next week.
Most of these whiners are probably in a tax bracket where they wouldn't even be paying capital gains this year, so it truly would have been free money.
