Oh. And with my job I have the unfortunate requirement of having to use a number of windows-only applications on a regular basis.
Many of these applications are, in fact, virtualized and are individually remote'd to my desktop. The way it is done is completely transparent and there is not a single non-technical user on a corporate windows desktop that will be able to tell you what applications are remote and which ones are local. They will not even be able to tell you that they are using virtualized applications remotely at all.
The experience is completely integrated and there is no discernible way, in terms of performance or image quality, to tell the difference between local and remote apps.
