Yeah, the only problem with Samsung is that they most likely going to make builds for the Exynos based SOC which isn't that wide spread.
The ARM ecosystem is quite fragmented and depending on how you build your software it's not as portable as one would assume.
It's also not clear which instruction sets they are going to be aiming for Exynos started with ARMv7 + all the stuff that Samsung added to it, but the newer ships are ARMv8.
The Raspberry Pi still uses ARMv6, 7 and 8 depending on the exact model with the newer RasPi compute, and Zero models still running the old BCM2835 ARMv6 CPU's.
So I'm hoping for a more or less clean stock ARMv7 and ARMv8 builds for the .NET core coming out sooner rather than later, I also hope they'll release the X86 version to more platforms than Windows since running it on something like an Intel Edison which comes with a 32bit ATOM CPU will be quite cool.
.NET is quite powerful and for my taste it's considerably better than Node.JS (I don't like Javascript, this isn't some technical observation just personal preference) but I do like C# and F# quite a bit and having the ability to run the same code across multiple platforms makes me excited for IOT/Embedded devices again especially considering that I don't have to work through some of the headaches that come with Mono (some pun indented).
