I am very new to .NET so please forgive me if this question is a lame.

From the reading that I have been doing, many people claim that passing data from tier to tier using a dataset or data table is a bad idea.

I noticed that the WROX book "ASP.NET 2.0 Databases" talks about using the new Dataset designer along with the ObjectDataSource control to pass datasets (or data tables) from the database layer to the presentation layer.

Does this mean that in ASP.NET 2.0 datasets have been improved to the point where they are the preferred (or at least viable) method of data transport between layers?
