Steve Lasker has posted a great whitepaper that describes the differences between SQL/e and SSCE. The document goes into quite a bit of detail on how the two solutions differ from an operations point of view (one runs as in-process, the other as a service etc). I think it stops short of providing any real guidance as it doesn’t give any good scenarios or examples of using either technology.
In addition it would be great to see more detail regarding the table of differences. One of the concepts that is referenced in this table is the ADO.NET Sync Framework. More information on this can also be found on Steve’s blog.
