Hi, Jay.
>Anything worthwhile that I can't do with the express version of 2005 that I can do with the 2003 that I have now?
If you are trying to learn .NET, not really. Even more, I would say that it would be a bad choice to try to learn .NET with the 1.1 Framework, because you'll spend a lot of time struggling with things that are much easier now.
For a complete detail of what's in the Express editions and what's not, see:
