No way. If there's one application that should be native on any O/S, that's a task manager. And not the Windows Mobile Task Manager. That's not a task manager, but an application that functions as one. There's a difference. A task manager should be native and as resource- independent as possible. If your device is locked up and nothing else works, you should still be able to bring up the task manager (usually with a hardware key) and kill that application that's bugging your phone. This cannot be left for third parties to take care of, as they could only create a workaround (a-la Windows Mobile Task Manager), not a real solution, which would most likely involve coding at the kernel
