I originally ordered the low end 2.1ghz white MB from Apple.com in August 2008. During the first week I noticed the top case was raised a little on the left side (seperated). I decided I would go ahead and experience an appointment with a Genius. I carried it in and the manager of the Apple store took a look at it and asked if he could just replace the notebook with a new one. I agreed and they migrated my data to the new one and I was on my way. Once home, I noticed that the specs were different. They had replaced my 2.1/120 combo with a 2.4/160 superdrive. I used my better judgement and called the store. I explained the situation and they told me they would research it and call me back. I talked to a couple of different employees throughout the day and finally I called back that night to check the status. I said I felt like they should know what they did. The girl looked at the receipt on their system and told me that the one I had originally brought in was in fact a 2.4ghz. She ensured me there was not a mixup. I checked the original box (they didn't switch the boxes) and it gave the 2.1 specs. She assured me that I brought in a 2.4ghz. End of story there. The receipt that I received from the exchange showed the serial number of my first machine but with the 2.4 specs. So, I paid for a 2.1ghz and ended up with a 2.4ghz. I got a $1299 machine for $999. This...a good deal. I feel like it would not be logical to sell my MB for way less than I paid and have to fork out more for an aluminum with a smaller processer, etc. Even though the new Macbooks are AMAZING, this white one does what I need it to. I ended up getting a great deal so I think I will keep this machine at least until the warranty expires.
