I just signed up for the ReadWrite Labs 7th Demo Day (Apr 04, starting at 5:30pm, San Francisco). Even though it says Demo Day, it's in the evening only, and is probably high energy, hipster and cool. I want to be all those things, so that's why I'm going.
If you're looking for hands-on IoT, this is probably not it. @craig is attending the 3-day Free Renesas Synergy Santa Clara Training (Mar 29-31) which is will be very high quality. And Medium One continues to produce excellent Renesas IoT Sandbox workshops like this one ("Wireless IoT Workshop: Sensor to Cloud in One Day" just conducted in North Carolina.
But if you are attending, please let me know. I have no inside information whether this is good or not, but I'm excited to spend a night in San Francisco listening to startups and their IoT ideas for wearable biometrics for athletes, smart lighting, energy savings, 3D mapping, and a ton more.
