You’ll be able to save non-RAW “slightly lower rez” pics simply by changing a setting on the back of the camera. If you really do want the ultra-high-rez pics, but don’t want RAW, on the D1 at least, there’s an option to store the highest-level as a TIF as well.

Don’t be scared of RAW, though, lots of applications (including iPhoto) all “get” RAW now. I seem to remember reading somewhere that while Nikon “owns” RAW format, it had opened it up more than it had previously been so as to foster increased use of it, not just with software apps, but also with other camera manufacturers.

I do think you’ll be really happy with the D200, though. Like JR says, you definitely need to post a review after a couple months of use.

Oh, and by the way, the D70 lets you shoot at lower res if you like. I also usually shoot high quality JPGs as the Nikon RAW format is more proprietary than I prefer (and frankly, I’ve yet to see an application where I need THAT much detail in common areas).

Either way, have fun!
