I called to switch but it shipped today...3 days early. I am sure I will be fine with it. Thanks to all for the detailed advice. I ordered a 24" with 2GB of system RAM and 128MB of VRAM. I do light video editing (iMovie, FCP), but mostly just browsing, email, web. Am I going to kick myself for not getting the 256MB option? Changing my order would slow things down significantly as it is due to ship now on September 21st. To be fair, I have been VERY happy with 128 on my 20" iMac Core Duo.
