I don't expect 99% of PostgreSQL/Win32 users to be developers. I hope we
see a myriad of apps built around a bundled PostgreSQL server, as well
as more advanced users looking to replace Access etc.

2 definate plus points.

Maybe.

Maybe. I think I have 3.5 at the office (we get most MS CDs a little
early). If I get time I'll look tomorrow.

What would scare me more is Microsoft changing the licencing terms in
the future. They already added anti open source clauses to the licence
of one of their products (iirc it was the Mobile Information Server
SDK).
