I'm settled in at Keystone for this year's Colorado Software Summit. If you haven't been before, this is a fantastic developer conference, rich with content and extremely casual. The format is unique: 90-minute sessions and each topic is offered 3 times during the week. So you are hard presssed to miss a topic, though there are certainly enough good ones you just might have to choose at some point.
I'm glad to see some less-than-enterprisey topics like Ruby and scripting on the menu this year; there is always plenty of SOA. But just as great are the hallway and fireplace conversations and the famous evening Q&A sessions. It might not be hard science, but I think the audience polls at the evening sessions are probably more telling than a lot of the "research" in industry mags. It says something when people are willing to trek this far and there isn't even vendor schwag involved!
