Palm OS, she is dead.

"Palm CEO Ed Colligan just pulled the plug on Palm OS... Colligan also mentions that the Pre will have an app store and Palm will have no control over the content. The Pre will hit other carriers in 2010 and that they’re not too worried about Apple’s patents (famous last words.) Luckily, Palm has 1500 patents up its sleeve and sees little problem in implementing multi-touch in the new OS."
