Well you've been harping on it for months, so I guess you figured out something else to worry about ... good to know you're so fickle.

There's not much more to discuss on that topic- MS either will or will not provide it. There are lots of other interesting topics. Change tracking is an interesting topic. Semaphore/reservation of records is an interesting topic. I really enjoyed hearing what others think, especially since it seems to be leading to a consensus that will be useful for anybody considering a move to NET. If that makes me fickle, then I can live with that.

ADO .net are in-memory datasets, so I don't see what the big deal is.

Take a look at Linq. It's not something you'll "get" until you do.

As I said, I'm enjoying the technical discussion with others here and don't feel inclined to participate in interpersonal disputes, especially on topics that the protagonists claim not to care about. If you've got some cool ideas about change tracking and/or account reservation techniques, I'm all ears.
