I have heard that DOs seem to be "nicer" because they feel lucky to be physicians. Apparently, they also tend to work harder than MDs, which is attractive to lower tier allopathic residency programs. DOs get an allo residency, allo residency gets hard-working residents. Not a bad trade off.
Someone should conduct a study that systematically investigates the differences between MDs and DOs. Such a study will likely involve hundreds of variables and a lengthy regression equation, but if conducted well, could confirm or refute some of the assertions made by people on these forums, the American Osteopathic Association, and physicians in the community.
People above indicated that a lot of the research on differences between osteopathic and allopathic physicians does not hold water. But why argue with anecdotes when you can argue with data? Here is some more research to chew on. This study was conducted by people at Harvard Medical School and published in one of the most prestigious journals of internal medicine:

OBJECTIVE: To contrast prevailing behaviors and attitudes relative to primary care education and practice in osteopathic and allopathic medical schools. DESIGN: Descriptive study using confidential telephone interviews conducted in 1993-94. Analyses compared responses of osteopaths and allopaths, controlling for primary care orientation. SETTING: United States academic health centers. PARTICIPANTS: National stratified probability samples of first-year and fourth-year medical students, postgraduate year 2 residents, and clinical faculty in osteopathic and allopathic medical schools, a sample of allopathic deans, and a census of deans of osteopathic schools (n = 457 osteopaths; n = 2,045 allopaths). MEASUREMENTS: Survey items assessed personal characteristics, students' reasons for entering medicine, learners' primary care educational experiences, community support for primary care, and attitudes toward the clinical and academic competence of primary care physicians. MAIN RESULTS: Primary care physicians composed a larger fraction of the faculty in osteopathic schools than in allopathic schools. Members of the osteopathic community were significantly more likely than their allopathic peers to describe themselves as socioemotionally oriented rather than technoscientifically oriented. Osteopathic learners were more likely than allopathic learners to have educational experiences in primary care venues and with primary care faculty, and to receive encouragement from faculty, including specialists, to enter primary care. Attitudes toward the clinical and academic competence of primary care physicians were consistently negative in both communities. Differences between communities were sustained after controlling for primary care orientation. CONCLUSIONS: In comparison with allopathic schools, the cultural practices and educational structures in osteopathic medical schools better support the production of primary care physicians. However, there is a lack of alignment between attitudes and practices in the osteopathic community.
