Below are notes from the first day off sessions at WWDC 2010. The biggest take-away is, the stunning revelation by all attendees that everything is moving towards mobile. After almost 2 days of sessions, Mac OS X was only mentioned in passing once, at which time the audience applauded. Many attendees even asked at loud , “Does Apple even have a Desktop or Laptop OS.”

Mobile devices are adding more and more features and hardware capabilities that are not available on laptops and Desktops.  i.e. accelerometer, gps, gyroscopes, magnetometer, forward and front facing cameras, facetime. The epiphany that many developers have had is there will be less and less need for desktops and laptops over the next couple years
