I agree with you somewhat, but you could argue that it could be derived in some shape for form since all the Arduino shields, I belive, are compatible with Netduino.

As you start wanting to pause your code and step through it to fix a bug in your code... And especially if you like event-based programming, garbage collection, and threading... Well, that's where Netduino becomes the only option.

That is probably the biggest + in my book.

I'm a newb here and don't actually own the netduino (YET!), but from the videos, it looks like a lot of the shields you can buy for the Arduino work for the Netduino, as demonstrated with the colorimeter video. I think the main difference is the development for each. Arduino uses it's own open-source code (similar to C#) while the netduino actually uses C# and the .NET framework. I think the main selling point for them is people who are software people and have a job and code in C# daily will be able to pick and use the netduino with a fairly small learning curve. But again, this is just my observations.
