While the technology for desktop virtualization has been around for some time, it has long had a perceived set of limitations, according to Register author Tim Anderson. Nevertheless, he adds, the modern versions of this type of technology go further than ever toward addressing those drawbacks.

For one thing, Anderson writes, it's no longer the case that virtual desktops can't handle graphically intensive work. Windows Server 2008 R2 SP1 allows for GPU virtualization, partially closing the performance gap. Furthermore, he says, desktop virtualization technology can switch back and forth between local and remote modes much more fluidly than in the past.

Desktop virtualization can also now be platform agnostic, Anderson writes. If, for example, a user wants to remotely access a virtual Windows desktop via their iPad, apps like Citrix Receiver can easily provide that functionality, he says.

When working remotely like this, experts say, it's almost always a good idea to use VPN technology to secure all communications between the user and the company's computer systems, particularly when wireless networks are used.
