Reread the article
The article stated that most of the XP apps were imported onto Vista. In addition, it's possible to show multiple OS's in the Boot feature when starting/restarting your computer. For instance, I run XP Pro SP2, Vista 32-bit and 64-Bit, Office 2007, Groove, Exchange. Now I do run custom computers, but I spend less than $1,000 getting them running and configured, along with the hardware I want. The OS IS backward compatible with nearly every app on XP, but with dual-boot feature, why do this? Also, Office doesn't need to be on the computer, I just have it and use it.
