Virtualisation reprise - Virtual Desktops

Since I was inundated by responses on my Virtual Licenses post, I've noticed that there is indeed a buzz about the community.

Microsoft has recently announced it is purchasing Calista technologies to enhance their OS's multimedia and 3D capabilities on Virtual Machines, which really puts virtualization in more of a consumer direction I feel. This could be good for those technologies, making them more mainstream, and opening up the massive desktop end-user to virtualization. This technology will work on any kind of virtual machine apart from Citrix.

Which brings me on to Citrix. Microsoft have announced that Windows Server 2008 will have more interoperability with Citrix XenServer. This will also help desktop managers use virtual desktop systems.

So what is the key advantage of Virtual Desktops - with so much push towards them in recent times?
This goes back to standard Desktop Management advantages really. A virtual machine is hard for the user to corrupt, and easy for the administrator to centrally change, update, and deploy. The cons of it would be larger hardware requirements, and the extra layer of technology can bring in new problems. That is why it is good to see all this new development around it, as this will lower those concerns.
