Well, I interviewed at Baylor, and am currently waitlisted there, and they insist on stringing me along mercilessly (giving me just enough info. to keep me going). I loved the school, although it might have been colored by the fact that it was my first interview, so I was just excited in general, and the fact that my SO is there. The biggest pluses in my opinion is the year and a half for basic sciences, which essentially gives you 10 "free" months throughout the rest of med school, so you can take time off to study for the boards, start clinicals earlier than most of your peers elsewhere, etc. Second, the clinical training just seemed like it would be superb. Apparently med students and residents basically run the county hospital, Ben Taub, so you have the opportunity for a ton of very hands-on experience.
The biggest negative is probably the location for a lot of people -- Houston is a city people love to hate. However, I've been there a bunch of times and it didn't seem that bad to me. Crime is definitely a concern, but I'm not sure if it would be any more of a concern than if you were at Columbia, Hopkins, USC, etc. Like I mentioned in the TX school thread, they can only accpet max. 30% out of state, so admission is competitive, but I definitely think it's a school worth applying to.
By the way, why wasn't Tulane wasn't on your list?
