It seems like Deb was reaching a bit for some of the myths. I don't think I've ever heard about Vista not being able to dual boot.
Also, when she's talking about video cards - I have it good. I have a nice video card that'll handle it just fine. However, I know that out of my entire IT staff, about 80% of them have video cards that have less than 128 Mb of video RAM, and older Pentium 4 PCs. Although a GeForce 5200 may be "inexpensive" for some, it still means that they'd have to buy an upgrade, and not everyone has $80 (that's just a random stab at how much it costs) to buy a replacement video card.
Add to that the ever-increasing senior population who are less up-to-date with technology, and you end up with a lot of people who will not be getting Vista without buying a new PC.
Personally, I don't like having different versions of Windows. It only multiplies the different number of operating systems I have to know about in order to troubleshoot if an issue gets to me. As much as I hate those biased, stupid PC-vs-Mac commercials, the latest one that talks about Mac only having one version DOES have some appeal.
