I e-mailed Amazon today to see if they had any plans to carry the 2.8 Ghz model and, for those interested, here was their reply: "Hello from Amazon.com. At this time, Apple 2.8Ghz 24" model is unavailable to us and we're not sure if we'll be able to obtain it in the future. However, you are welcome to purchase the other model "Apple 24"iMac model" at anytime you want. Also I would like to suggest checking our web site from time to time to see if this item is available from us or from another seller. If anyone is selling it, you'll see a "More Buying Choices" box on the product detail page; if it's not available from any sellers, you might see an "Order it used" or "Alert me" link. "Order it used" allows you to place a pre-order for the item in case another seller puts a copy up for sale later. "Alert me" allows you to sign up so we can e-mail you when Amazon has copies available for purchase. I'm sorry not to have better news, but I hope this information has been helpful." I'm still on the fence as to which one to go with myself...I think the 2.4 Ghz would be plenty sufficient with the RAM maxed out especially and I'd rather order from Amazon and get the points (triple if you use your Amazon credit card), save tax $, and hopefully get a rebate, not to mention that I 've ordered many times from them and their customer service is excellent...but...benchmarks are starting to come in on the 2.8 and it looks good so far-not to mention that I will be running Aperture. What to do....?!
