This year, at CommunityOne and JavaOne, every user has access (through their registration smart cards) to arrays of SunRay clients and a choice of Windows, OpenSolaris and Ubuntu desktops accessed through the SunRay clients. The system is powered by SunRay servers and VirtualBox virtualization environment. I'm using one of the SunRay 270's to write and post this blog. (I selected the Ubuntu desktop.)
