Thanks Apple… I feel ripped off
As I posted earlier, I just made the “switch” and bought a MacMini & a MacBook, mainly because of the iPhone development community. But today, Apple released a new MacBook with better specs for the same price I paid for mine only 2 weeks ago. I truly feel ripped off. 
I tried calling Customer Support, but they are closed until morning. However, I was able to chat with a support person via Apple.com, her name was Janet. As soon as I explained my plight, she quickly responded with “Call Customer Support, they are handling all purchases made Feb 7 - Feb 26.” That was good news to hear… because my Apple Store receipt is dated Feb 9!!!
I hope I get the new MacBook this week.
2.4 C2D, 2GB RAM, 160GB HD 
UPDATE: [02/27/08]
I went to the 29th Street store in Boulder and after talking to CS on the phone and the manager Josh & Jeff said they would allow me to switch it, however I had to pay the 10% restocking fee. All in all, it was worth it, just the extra 1GB of RAM (from Apple) is worth the $130.
Thanks Apple!!
