Sorry to keep this dragging on but will these features effect my usability of the OS? I mean if it's just eye candy that I will be missing then I guess that I can live without it but if it's actual usability that's a different story. I guess I want to take advantage of this 200$ back plus Ipod deal as I can trim a lot of money off of a new iBook with apple care and the works. Thanks for all your help so far though!
It won't affect basic usability. Websurfing, email, word processing--these things will still work. Apple is a responsible enough company that Core Image is designed to scale down gracefully--current iBooks will work seamlessly with Tiger, it's just all the special effects will be missing. But eventually, the new eyecandy is going to lead to a lot of new features. It's sort of like marketing a boring yet useful product--say, a toolbox--with a beautiful woman in skimpy clothing. Apple's inked a deal with all the web browser developers except Microsoft to revamp the standards for browser plugins. This is connected to the new Dashboard feature, which in turn is powered by Core Image.
Basically, Apple's moving towards a vision of the Internet where little web-based programs can run independently on the desktop. I don't know how long you've been a Mac user, but back in the mid 90s, Apple invested a lot of money and time into researching object-based operating systems and applications. The next-gen Mac OS codenamed Copland (this was before Jobs returned and OS X dev started) was going to be based on this technology, called OpenDoc. Instead of applications that could do anything, developers would have built small application components that could be tied together to do anything you wanted. A quick google search actually turns up an OpenDoc developer, back in 1997, boasting about how "It's easy to build an information 'dashboard' with OpenDoc parts and Java applets and other elements." OpenDoc wasn't about eye candy. It was about letting ordinary users do extraordinary things with their computers, without having to learn a programming language. With the new Automator in Tiger, and Dashboard, it seems Apple's decided this is the time to implement those capabilities. Right now, Dashboard widgets are limited to revamped Desktop Accessories--clocks, sticky notes, puzzles, etc. However, since they're written in HTML using CSS and Javascript, there's going to be crazy interaction with the web. Apple's preview of Tiger (10.4) has a stock ticker/graph which hints at these possibilities. For more info, there's this blog entry that got highlighted by Slashdot this morning:

Because these Dashboard widgets are so easy to write (compared to regular programs), it's likely developers and computer science students will go crazy with them. Because Core Image interfaces with OS X's innate video capabilities, it is also likely Apple will find ways to tie Dashboard in with QuickTime and iMovie/Final Cut. Here's what the page from the Tiger preview says:
Core Video provides a modern foundation for video services in Mac OS X Tiger. It provides a bridge between QuickTime and the GPU for hardware-accelerated video processing. This highly-optimized pipeline for video presentation increases performance and reduces CPU load, freeing up resources for other operations.
And Core Video allows developers to apply all the benefits of Core Image to video blazingly-fast performance of filters and effects, per-pixel accuracy and hardware scalability.
That's a lot of marketing talk, I know. I'm not quite sure what it means, either. It seems to indicate that Core Graphics will speed up Mac OS by offloading processing from the CPU to the GPU, at least for video. So it's possible that the current iBook won't be able to take advantage of a speed boost in Tiger--though it certainly shouldn't get any slower with the new OS.
The bottom line is that the iBook is a great, reliable, rugged, efficient, portable computer. If you buy one now you will be happy with it. It can do everything your 500mhz iBook can do--and a hell of a lot more. The iBook G4 isn't just Apple's most affordable computer--it's also, arguably, the best deal Apple's ever had for consumers, especially students. If you buy one now, come January, you will just be missing out on some eye candy. Come the January after that, you might be missing out on a lot more, as developers figure out how to do Really Cool Stuff with these new system-level visual effects and modular programming. A new iBook that can do that stuff is probably coming in the next six months, though certainly not before the new iMac is on store shelves. But that's always true with computers. To answer your question about pricing, it is likely there will be no change, or if there is, only a minimal one. So do you really want to wait half a year? It is quite likely you will get more enjoyment out of a ridiculously cheap 3G iPod and a current iBook (both of which will be 'obsolete' in a few months) now than you will from a slightly better iBook and a ridiculously expensive 4G iPod in November.
