So let me get this straight...
Some of you have reservations about getting the full-monty 24" iMac because of the additional price (and heat) of the 3.06GHz processor, but you then go ahead and get the 2.8GHz iMac with 4GB of RAM preinstalled?
You can (and should) order RAM elsewhere and install it yourself for half the price. Sell your 2GB of existing RAM and pretty much get 4GB for free.
I agree. Got a quote today from my local vendor (Sydney, Australia). The Apple website charges $300 for the RAM upgrade from 2GB to 4GB. However, the vendor will charge slightly less than that for 4GB of Kingston RAM... AND give me back the standard 2GB that comes with the iMac (which I can sell if I want to). I think most people should be able to get a similar deal from their vendor.
