All your points (well, aside from mingw itself) are great ones. Cygwin is 100% a monster. But it's a monster that works the way I expect it to. MSYS is often lacking in things I consider basic that I miss going from OS X to Windows and trying to configure it is a super-pain-in-the-ass.
Colinux is actually pretty cool, but the need for an X server and the setup time is a pain in the ass.
