I have not been given a delivery date. I paid for the express FedEx delivery, so it should be here is 8-13 days--between Feb 5th and Feb 12th. Based on my experience with Apple, they tend to come in earlier than predicted.
My system:
2.93GHz Processor
4GB RAM
256GB SSD
Glossy Display--I think it looks better than matte.
Also ordered Final Cut Express and Aperture, and Apple Care.
For the price you'd pay for this at an online retailer without tax, I got the same thing direct from Apple Store after purchasing select membership at the Apple Developer Center (ADC).
The plus was I have access to ADC resources, and have access to early versions of software, etc.
I am a bit worried about what sort of SSD I will get. I'm hoping it will have the new Samsung drive. If it is not fast enough I'll move whatever it is into my Mac Mini and buy the Samsung drive later on when it is available on the street.
I noticed DDR3 memory is dropping. $903 at Memory America. It has dropped $200 in the last few weeks for 8GB (2x4GB) Ram. I don't think I'll need the extra Ram with the SSD, so I decided to wait on that. And it is still way cheaper at Memory America than at Apple.
