This is another reason...
...why larger companies are going down the route of desktop virtualisation, or at least looking very closely at it.
Company I work for uses thin clients (embedded Win 7) to open up a shared virtual desktop, which is based on Win Server 2008. As its a server OS, they have more control over the updates, and can pick and choose.
For any user requiring anything more flexible (devs, sysadmins etc), then dedicated virtual machines can be provided (win 7 pro at the moment).
For myself, i'll probably let my home desktop bump up to 10, but then thats mainly to allow xbox streaming. My laptop will remain where it is for the time being, as i use that more for everything else.
