More Vista on a Mac

I'm having problems getting Vista and OS X to co-exist. I
successfully installed Vista on the iMac, but that was with
formatting the disk in the Microsoft installer, which then left me
unable to format the additional partitions as HFS+ for Mac OS X later
on. Vista booted fairly quickly, I seemed to get the whole user
experience, Aero Glass looks quite nice, with the realtime shadows
and blurry transparency, most hardware in the iMac was detected, one
exception being the AirPort card, however I was surprised to see the
iSight in the Device Manager.
Anyway, I've erased Vista, reinstalled OS X and am now trying more
Boot Camp action to see if I can get them to co-exist.
