Two factors that haven't been discussed that might be relevant: timing of application, and "other non-quantitative aspect of application"
1. Are you applying late in the application cycle (for class of 2008) or applying to next year's application cycle (class of 2009 or later)? You might have the stats, but applying late in this cycle puts you at a disadvantage.
2. Non-quantitative aspect. As many have stated, DO schools look past the numbers. That can work for or against you. Your stats are fine - but what about other aspects - healthcare experiences, knowledge of osteopathic medicine and history, goals and motivation, etc. How well do you interact with other people? You can have great GPA and great MCAT, but if the admission committee feels that you wouldn't be compatible with the student body, then you might not get in.
You have a good gpa and a decent mcat (depending on breakdown). However, also be aware of other factors that might come into play. Remember, DO schools are known to look past the numbers
