If the dates announced are just estimations like they said, i've nor reason to believe my powerbook will even ship on or before march. So, they have no idea when their products will ship.
Apple over promise and under deliver. I think they should under promise and over deliver instead. It's like when they say the ipod photo has 15 hours battery life. I would be more satisfied and feel less cheated if they were a little bit more honest. I like their products a lot but i'v had no luck with Apple recently (see my post: My powermac g5, 2 months in hell).
I've also bought an iPod Photo and tried to register it on their sitebut my serial number has been refused. Again, i didn't get any answers to my emails about this issue.
