    Hi Chris-  Great post.  And ironically two of the emails you showcase, Sony PlayStation and Amazon were developed out of our shop, Euro RSCG Discovery in Baltimore.  Ironically, I see you work at ExactTarget, our preferred email service provider.  With initial open rates about 40% or more on mobile devices versus desktop, we see great value in responsive design techniques and the results have paid off significantly, with not a whole heck of a lot more labor to accomplish it.  Hopefully you’ll be the recipient of more responsive emails coming out of Discovery soon.
