Web Parts and ASP.NET 2.0
Dino Esposito has a nice summary article over at TheServer.NET on his thoughts around ASP.NET 2.0, the Web Part framework it offers, and ideas around where SharePoint could/should go. In the article he designs a realistic component and build it as a SharePoint WebPart (an Amazon search tool) then he builds the same component as an ASP.NET 2.0 WebPart. For awhile we'll have to be playing catchup as ASP.NET 2.0 comes out, then an update to SharePoint to match. In the end they'll be a convergence, just hard to see where or when that will happen so in the meantime we just struggle along our way.
