I'm exactly the same way unless it's an email I am interested in or if it's from a sender I care to hear from. However, if it's an html email from a sender I care to hear from, but I open it and I have to scroll sideways just to see parts of the image... I will delete it immediately, and won't download images from that sender in the future...

Responsive emails probably won't help with emails you don't care about...But, emails you are interested in, it can make all the difference.
