Every time I consider a Nokia / Windows Phone device the problem is either that Microsoft is too slow to release updates thus limiting both their OS and the potential for phone manufacturers like Nokia to produce up-to-specifications devices. Or Nokia is incapable of producing their phones in enough bulk to supply the customers for whatever the reason.
And the supply-chain is always focused on the US, where they have the fewest customers. Europeans have to wait. And Americans are stuck with the torment of carrier exclusives, so it's not like they live in a paradise. From what we've seen from Microsoft so far, that US-centric approach will just get worse with them at the helm.
It's always too little too late from Microsoft/Nokia, and it makes me sad. Unless they can pick up the pace, I'll undoubtedly go with either the HTC M8 Prime, LG G3 or OnePlus One. I was so dreaming of a 1030 by summer...
