To the best of my knowledge, you can save your version 6 or 7 notebook
and open it in versions down to at least 5. Given that it is plain
ASCII earlier versions should be able to open it. The Notebook[ ]
function appeared in version 3, so I guess that presentable results
will be possible as old as that.

Whether or not you can use it is another thing. Obviously, as the
version number increases so does the functionality and you can't use
the added functionalities in older versions.

Other compatibility issues involve existing functions that have
changed in options (like the PlotJoined to Joined change in ListPlot)
or behavior (like the output of graphics shown as a direct result of
command execution instead of being a side effect and consting of
Mathematica primitives instead of postscript).
There were a few of this type going from 5 to 6, but I haven't seen
many going from 6 to 7. Some functionality from packages has been
moved to the kernel.

Cheers -- Sjoerd
