I have an app developing that will include several wireless handheld barcode scanners running SQL Mobile, operating simultaneously alongside a winforms component. I am using SQL merge replication and RDA and like the concepts and implementation so far.



Now this works best with GUID primekeys so they are guaranteed to be unique across replicated copies of the tables on the handhelds.



So the question is this, any tricks or "things to know" when using GUID primekeys versus integers (as I have always used) in the framework? Do you recommend the default value of newid() ?



As always thanks for the insight.
