Response to: Pros and Cons of Session state and View state in SharePoint webpart

Revision 6
I use ViewState all the time. And it works good, PROVIDED that the SIZE of the data is "reasonably bounded" for the given network-access scenarios. So the question is, "HOW BIG?" is the data when PERSISTED to the ViewState hidden field? If this is "too big" or not depends primarly upon network conditions; the ultimately issue with ViewState isn't that it must be downloaded, but rather that it must be sent BACK with each request - and connections are sometimes asymmetric in performance. Just avoid using a DataTable as the default Serialization it uses works poorly with the serializer used in ASP.NET (which is quite efficient for primitive structure trees and collections that don't muck with a custom serialization).
