You know, beleive it or not, Apple SOMETIMES listens to feedback about announcements and pricing, etc. If you are one of the ones who just purchased the latest PB 15" FW800 and were excluded from the free upgrade, CALL THEM!!!
Call 800-767-2775 and ask to speak to Customer Relations (or whatever the prompt is... NOT the store)
Explain the situation with your new hardware and how its release is so close to the cutoff date for Panther and ask them to log your suggestion that they include the new PB line totally. Maybe this will make a difference.... it might...
Be nice too - helps!!
