Palm OS is dead?

I'm a little slow (I'm sick) - so this probably wont be news, but with the annoucements by PalmSource this week many are claiming that Palm as an operating system is dead.

Engaget started it by reporting that Cobalt (Palm OS 6.0) was dead and that development was switching completely to a Linux based OS.

Pocket PC Thoughts has an article on it here which wonders about the sustainability of their business in the short term.

Even Kent from who is a Palm fan claims its true.

I dont know if it will actually turn out as bad as they suggest, but they've had a hard time getting any devices to use version 6.0 of the Palm OS which was released in December 2003.  Its an interesting situation to watch if nothing else...
