Peering and Network Cost

IX port pricing in the Chicago area has plummeted in the past two or three years. It's gone down... maybe 2/3.

You appear to be assuming that an IP transit port is more expensive 
then an IXP port with the same speed. That doesn't seem to always be 
the case anymore, at least not in all parts of the world, and I expect 
this trend to continue - transit prices seems to go down almost on a 
monthly basis, while the price lists of the two closest IXPs to where 
I'm sitting are dated 2011 and 2013, respectively. 

Even if the transit port itself remains slightly more expensive than 
the IXP port like in the example Baldur showed, the no-peering 
alternative might still be cheaper overall because even if you're 
peering most of your traffic you'll still need to pay a nonzero amount 
for a (smaller or less utilised) transit port anyway.
