iPhone SDK
You can read about some of my initial reactions to the iPhone SDK announcement today over at Mactropolis.com.
Summary - yay!
Update: Enthusiasm dampened - the developer program is only open to U.S. residence for now. That means no running applications on the actual device for me, only the simulator (which basically means it’s next to impossible to develop any accelerometer-based applications). The reasons for this restriction are not entirely clear to me, iPod Touches are available worldwide.
