Here's some (biased?) sources:

[Improved endurance capacity ->] http://article.pubs.nrc-cnrc.gc.ca/ppv/RPViewDoc?issn=1715-5320&volume=34&issue=1&startPage=78
[Stimulates muscle protein synthesis ->] http://journals.lww.com/acsm-msse/Abstract/2006/04000/Milk_Ingestion_Stimulates_Net_Muscle_Protein.9.aspx
[better than soy ->] http://www.ajcn.org/cgi/content/abstract/85/4/1031
And there are some folks in my household that are not very happy with this choice ... they'd prefer I drink some multivitamin-supercharged green-tea-infused black-current-goji-juice-soy with Himilayan-Lama-nut-extract crap that costs more than our cable bill and tastes like freshly-cut-grass juice.
I hope that person doesn't read my blog, cuz I can kiss those massages goodbye!
I want to thank Rudy for the great link to the milk marketing board. We need someone defending the antibiotic-filled, over-crowded, cattle-torturing milk factories. I have one word for all you haters: "Moooooo!" I'm a convert.
