There is no real distinction between the two lines it seems (to me). But I do notice the DX seems to have better lenses and speed. Also the price reflects it.
Let me share that I enjoyed my DX6490 on an 8 day trip and it performed very well. If the 7490 or such is a significant stepup, I may consider it sooner than later.
The one thing I learned was to pop open the flash when in doubt.

I, too, am looking for my 1st digital camera. I think I've narrowed it too the Kodak DX7440. But now I see Canon has an A85 (a friend of mine has the A80 and loves it).So what's the difference between Kodak's CX and DX line. And should I maybe plan for the future and consider the Kodak DX7640 ?
