VMware, Citrix and smaller rivals are putting clients on smartphones and minimalist thin-client hardware to build excitement for Virtual Desktop Infrastructures (VDI). Here’s a look at why both Citrix and VMware believe that Windows 7 will be a major catalyst for desktop virtualization, though customers still have management questions. “VMware and Citrix both announced support for the iPhone, which’s sexier, even though Blackberries’ve a greater penetration in business,” Mann says. “Virtualization on handhelds is a kind of halo project —like the Chevy Corvette that dazzles customers who come in and end up buying a Chevette.” “Windows 7 is going to drive a lot of the activity around desktop virtualization for companies that want or need to upgrade to Windows 7,” Wolf says. “Strategically, both Citrix and VMware have been planning that Windows 7 would be a major catalyst for desktop virtualization, and have been working toward it for a long time,” Wolf says.
