Here are some random comments:
- One of the IronPython guys was a "reformed" Ruby on Rails guy ;)
- One of the guys didn't even like Windows, but admitted, "Windows Forms is nice."
- C# doesn't have first class functions.
- The ability to use Windows Forms and IronPython together is a great boon for .NET developers.
- If you're going to use this stuff, buy the full version of Visual Studio instead of relying on the free version.
