ASP.NET Web Services or WCF, which one to choose?

There's a new article available on MSDN that details the differences between web service implementation on ASP.NET 2.0 and Windows Communication Foundation or WCF.

If you are about to start developing Web Service (WS) applications with Visual Studio 2005 (or, Delphi .NET for that matter), then you should take a look of this article. My opinion is that presently, for smaller projects ASP.NET web services architecture is a good choice for growth path for the future. However, for larger projects that take time to plan through, it might be wise to wait until WCF is here (think Vista).
