core image

You do know what CoreImage really is right? It's not a rendering engine. It's an API.
Absolutely correct. Coreimage has to be the most misunderstood thing about Tiger. As I understand it, coreimage will look to see of you have a programmable pixel level graphics card
for those effects that actually benefit from pixel programming Not all of coreimage's effects require it. If you don't have a pixel programmable graphics card, coreimage then looks to see of you have an MP cpu system and uses the additional proccessor along with altivec. If you still come up short, core image then optimizes for altivec proccessing on a single G4. So it can fall back no problem if you don't have a pixel programmable graphics card living in your system. I don't know how G3 machines will deal with it, since they don't have altivec. Things might get a little slow there.
Think about it folks. Apple isn't stupid. They aren't going to release an OS that only the most recent, most powerful machines will benefit from, because they aren't going to sell very many copies of Tiger if they do. They have invested millions in the development of Tiger alone. Obviously, they want Tiger on as many machines that are in use now as they can possibly hope for. And they are looking to impress with this release, not dissapoint. I expect my 1gigahertz eMac with its "measley" 32 meg Radeon 7500 proccessor to fly on Tiger, just as it does with Panther right now. So the Mini, with even better hardware specs, will certainly do no worse.
By the way, the much vaunted "ripple effect" that was seen in the Dashboard demos? If you have a Mac that came with the World Book encylopedia, you can see it right now on Panther. Thats right, no need to wait for Tiger just for that. Open up World Book, and when you see the introductory aqua screen, with the floating pictures scrolling from left to right, click on any part of the screen that doesn't contain a link. (Don't click on the scrolling pics, because they are links) You will then see the famous "ripple effect" sans coreimage
The only thing i can honestly say about Tiger is that I can hardly wait. AFAIK, with Tiger's feature set this is poised to be the best, most significant operating system release since the introduction of the original Mac OS
