    Core Image will take advantage of a computer's GPU rather than the CPU.

    In basic layman's terms:

    To the developer it will mean that it will be a lot easier to code apps that will take advantage of the GPU. With Image Units, theoritically at least, smaller developers will be able to compete with monsters like Photoshop on a functional level

    To the consumer it will mean things like real time rendering time, less bloated apps and features that would have been impossible before. Less CPU load should make your computing experience feel snappier/look a lot better!

    A very, very basic outline to a very promising and exciting bit of technology! ;)

    A common misconception is that Core Image is basically Quartz Extreme Extreme. This is not the case. Core Image is only a set of filters, similar to the filters in Photoshop, which OS X provides as a framework for developers and are rendered in real-time on the GPU. Core Video is the same, only with video.

    What this means is that you could soon see some reasonably cheap alternatives to Photoshop. The main problem with creating a Photoshop is that it takes a LOT of time and money to write the pixel-level code necessary to create its filters. With Core Image, the work's already been done. Of course, there are other applications that could use Core Image, as it is not limited to editing documents, but this example is the one that springs most readily to mind.
