Quote - and, well, I have not had these issues after I configured it correctly,

The problem isnt the teething hardware/software troubles that Vista is having, cause those will go away soon enough as companies release better drivers and MS release service patches.

The real problem is that Vista has very draconian DRM services that are open for abuse by anyone that feels like it. So eg if tomorrow DAZ, eF or other merchants feel that their software/content aren't being protected well enough, they can start adding DRM keys to whatever they sell. If they do this, it will mean that every poser user that buys their content will face the exact same horrible DRM measures that video/audio users are facing now.

So your content wont work on anything but poser, you will not be able to edit or load poser meshes for reference on anything but poser, you will not be able to hand edit any poser file, you will not even be able to view any customised poser meshes on the latest large format displays. And if you do manage to do any of these things (even if it is all innocent), Vista will invalidate your keys, disabling not only your content, but also your graphic card drivers, your copy of poser, and any other software you may have been using to edit. And then it will not enable them again till you to buy/get a new set of keys for stuff you have already bought once.

This is exactly what happens in the case of HDTV video/audio on Vista right now, and it will happen the same way for any other DRM protected stuff running on Vista. It's a merchant's wet dream of course, but i'm pretty sure most users will not be happy, not that anyone ever listens to users.
