I have the base model 13" MBP in my possession, but I have been trying to return it for a 13" 2.53ghz machine since last Friday. And even until today, they have been out of stock of this particular model. I have called all the Apple Stores in my area and they have been out of stock for about 5-6 days. I checked the online store and all 2.53ghz models (13" or 15") are backordered 5-7 days. All other models ship within 24 hours. So, what are your experiences at your Apple Store in regards to the stock of 13" 2.53ghz model? Are the higher end 13" selling this well, or could there be a problem producing/sourcing enough 2.53ghz processors? I will continue to wait until they are back in stock until then.
