I've invested years of my life in Swing development, so its a little scary to even pose the question, "Is Swing Dead?" Our largest customer, a major US bank, used to do a significant amount of Swing programming. These days all new projects are using WinForms, WPF, or Flex. All of these technologies are very good, and have big marketing bucks behind them (Microsoft and Adobe respectively.) With Sun gasping for air and IBM backing a competing toolkit, what will happen to Swing?
