I dunno if I would be so quick to say there is no difference, especially with a capital no. It's a fundamentally different approach to healthcare. Yes it's equal in terms of physician status, scope, etc. and maybe even respect these days, but it's definitely separate. And maybe they don't treat the "whole body" so much anymore, but they absolutely consider the whole body more so than MDs, who treat disease by specifically targetting the symptoms, at least that's the generalization. The flipside tho, of course, is that MDs and allopathic schools are beginning to become more holistic in
their treatments, so in that sense you might be right.
Still, there are many many people that go DO instead of MD because they don't like the very scientific-just-treat-the-symptoms approach that MDs subscribe to. And while maybe the textbooks are the same, that philososophy difference is definitely felt throughout your education.
And hell, forget altogether my original question about pod school, here's a nice article, even, about the differences:

This quote from it sums things up pretty well i think, "In actual practice, the variations between the two types of physicians are often so slight as to be unnoticeable to patients, and a day in the life of each can appear indistinguishable. But the differences are there, subtle but deep." (i think the same goes for your education)
