I don't have time to search through the countless forums here, so if this has been covered numerous times, I apologize. What I don't get is what this means exactly (core image) for computers with graphics cards below the requirements. I have an imac 800 and an ibook g4, both of which don't meet the requirements. Does this mean that the dashboard widgets for instance will not have the flip effect on my machines? Am I going to be missing out on a lot of the key features/future potential software releases for Tiger? (not trying to imply that flipping widgets is in itself a key feature).
