Sometimes sleeping on it makes all the difference in the world.  In a few short days it will be in my hot little hands. I hate the arms length thing between Handspring and the service providers, though:

By proceeding with purchase, you agree that Handspring shall not be responsible for any matters relating to your wireless service contract with Sprint. If you return your Treo 300/600 in compliance with Handspring's return policy , you may still be required to pay a termination fee to Sprint unless you cancel your Sprint service in compliance with the Sprint terms and conditions .

Or maybe it's just Sprint:

 ** ATTENTION: Please note that Sprint will charge you a $36 ESN swap fee to switch your current service plan to your new Treo 600.

Anyway, yippee, can't wait for my 600.
