J324K, I hope you won't spend your precious pre-med time worrying about this stuff. Its hard enough to get into medical school much less go on to match in surgery. Enjoy what you are doing now, these are good times! Good luck to you, remember to keep an open mind about things.
Surgeons and surgical residents still work harder than anyone else, that is well-known. Our field is for people who like to work hard. That said, surgical residencies in general involve less hours in the hospital than they used to. The changes I have seen over the past 10 years are remarkable, although like others have said, our residents still work a lot. And because our residents aren't in the hospital as much, things tend to be busier when they are there, so those 90 hours don't involve any down time if you will.
You mention hearing about difficult programs. Years from now you will realize that the most selective places are often given the "malignant" label that I hear students talk about these days. Surgical powerhouses like Duke and WashU and MGH and the like continue to attract top applicants from around the country. Of course top applicants go elsewhere also, but these places year in and year out get to pick the best of an incredibly outstanding pool. I don't think these residents necessarily work a whole lot more than residents at good community programs or lesser-known academic programs, but perhaps they have more responsibilities in addition to patient care, namely research. It is also worth considering that traditional top programs like MGH, Duke, etc attract medical students who love the term you use, "old school," to them it means excellence.
