When I think back to the first Linux Foundation Collaboration Summit, I start to realize how much work the community has gotten done over the last five years. Since meeting at Google's headquarters in June 2007, we've seen real advancements for Linux in super computing, cloud computing and virtualization. There are really interesting things that have happened around high-availablity (HA), for example, that you will see first-hand at the upcoming Collaboration Summit. Working Groups at The Linux Foundation have also been hard at work on Accessibility, Networking, Device Drivers, Open Printing and Open Compliance, just to name a few. But perhaps no area of computing has gotten the attention in recent years for Linux as mobile and embedded. And, of course, this is one of the primary areas of emphasis on this year's schedule.
