The linked forum has already done some work posting links to manufacturer's sites about Vista drivers, compatibilty, etc. (I hope it's OK to link to another forum. I realize this is the best. but info is info, right?) May be a good place to start investigating if anyone is considering "upgrading" to Vista (so you can learn how to disable even MORE unnecessary Microsoft "features".)
Even if the content may not be absolutely current, a lot of the manufacturer's links and comments are in one spot, so you may find your hardware or software, (or what you are considering buying) and get some idea as to where they're at.
