Can virtual pc's get linux on your desktop?

I came across an interesting article today over at techworld.com about the issues with migrating to a Linux Desktop.  The article makes serveral really good points about whether or not you will really see the R in the ROI and how Virtual PCs might just finally make it all work out for companies of all sizes.  The trick is, as it's always been, getting people to do things they aren't familar with. 

What do you think, can Virutal PC's enhance Linux Adoption?  Let us know in the comments below.
