From a techie point of view, it’s not clear that it’ll make much difference. We’re still different products and different teams, with not too much overlap.

I guess it also demonstrates a true heavyweight presence in this space (as if that were needed)! Sun is of course the provider for Glassfish and MySQL (among other things) by virtue of owning them – albeit by acquisition in the latter case.
