In addition to Chris DiBona's words about NVIDIA and ATI
binary display drivers, Google had also made an interesting splash at
the first-ever Linux Foundation Collaboration Summit (which they had
kindly hosted at their Mountain View campus) during a presentation by
the Google Linux Client Team. What was it? Well, there are some
"significant accomplishments" and other new Google desktop applications
coming out this year for the Linux platform.
