I have one of GHI's budget offerings in arduino form factor, the FEZ Panda II, and I really like it. In terms of quick prototyping and debugging I think the .NET Micro-framework is a hit. However, I don't see it being useful outside of the hobbyist/prototyping domain. The run-time environment would be considered too bloated for the purpose of simple embedded systems (by simple I mean without an OS/RTOS) and requires more expensive hardware to support it. However, I'm quite happy using C# and the .NET libraries! I'm putting together a wireless sensor network with a coordinator that doubles as an embedded web server to control various things via a web interface :D. Development time has definitely been reduced compared to writing everything in C.
