Crowd funding projects really only works when products are consumer-focussed and with unique selling points, so I'm not at all surprised. In this case, awareness of the USPs of Windows 10 Mobile and people with crowd-fundung cash to invest don't really go together.
I was hoping that Trekstor might have had a sugar-daddy investor waiting to leap in, but that didn't happen, at least not in the public campaign.
Leaving the current actively sold Windows 10 Mobile (new) device stable at the 400 (or so) Euro Alcatel IDOL 4 Pro and the 200 (or so) Euro Wileyfox Pro. So there's some choice, though it's all rather pitiful compared to the variety in other ecosystems!
