Why a different NEF for each new model?

Simple. There isn't.

Obviously talking about Nikon RAW  but the question could apply to other brands and their raw file format.

So why does each Nikon camera model apparently have its own NEF format which often leads to problems with software compatability (eg unable to open in adobe camera raw until the software has been updated).

Because Adobe likes making their raw processing programs only process "known" cameras. That insures pressure to upgrade the Adobe programs frequently.

You should see how complex the interlock mechanism that keeps new versions of ACR from  functioning with older PS versions is.

Really, Nikon, Canon, etc. do not change their raw formats with every camera, so a raw processor that reads the headers properly can decode all the data. There's a difference between just "reading" something and really understanding it, though. The best raw processing programs lag behind the camera releases because they typically use parameters measured from actual cameras for noise processing, anti-aliasing, color processing, sharpening radii, etc.

You can't get around that, unless you want the sensor to not change between new cameras.

What is so different about each camera type of raw file that makes them disimilar and why can't they all be the same or at least compatible?

They are "at least compatible" so your question is meaningless.
