Anyone who is serious about the future of openess, freedom and privacy rights in software and general should strive for the original. I advocate not to hand over MS the control over the Linux desktop.
So yeah, nothing to see here, if anything this is good as it makes linux more accessible to people stuck in windows-only environments. This isn't even M$ making a desktop environment. They have just written an X server into windows instead of having to install one yourself.
side note: I'd also be quite happy if Windows slowly removed the windows parts and replaced them with unixy parts until the whole windows ecosystem could be considered unix-based. That would be so great for so many reasons.
I don't agree with those feelings, so it is indeed the best GNU/Linux experience for me.
