While some will find this news difficult to accept, these three icons from Palm's original mobile computing business have had a long service life. The Tungsten E2, the oldest of the trio (not "Treo"), was released in April of 2005. I am not aware of any other Palm device that enjoyed a 4 year service life. Not even the wildly popular Tungsten C had a shelf life of that long. The remaining two PDAs, the Z22 and the Palm TX (sometimes referred to as the "Tungsten T7 or Tungsten X) where both released in October 2005.

You will still be able to purchase Palm's handheld PDAs from the Palm online store and other retailers until inventories are fully depleted. If you are interesting in purchasing the last flagship handheld, the Palm TX, Palm is currently selling the PDA for $199 (regularly $299) at their online store. Palm's online store also has the Z22 on sale for $99 (no discount). It appears that the Tungsten E2 is completely sold out at the Palm online store.
