At a personal and professional level, I was impressed with quality of the conference; each presentation had something for most, and the cosy arrangements by the Meydenbauer Center staff with a constant supply of quality coffee (this was Seattle ) and snacks, along with tons of table and chairs for impromptu meetings created a great atmosphere. Conversations ranged from details of instruction sets to programming models to business models. 

There were a number of great presentations made as well, including a number of though provoking keynote speeches which I really recommend. 

Looking ahead, there is clearly going to be a ton of activity in this area, as OpenCL and other programming methods become more accepted on Windows, MacOS and Linux on the server, desktop and portable application areas. On the mobile handset / tablet side of things, the impact of Android and Google's approach to things will clearly have some impact. It is too early to say what will happen by this time next year - except we all know there will be constant change.
