My comment is going to be down voted into oblivion but I think startups ignore Windows Phone and BBZ10 at their own peril.

I currently own a WP8 and it's a lustworthy phone. I see a lot of opportunities for app developers. I'm hearing good things about the Z10 too and friends are buying it. Not many apps though. Not much competition it seems.

Reminds me of the saying "In the land of the blind, the one-eyed man is king."

Okay, perhaps they are nice devices. But, from a startup point of view, the fact that they are small current markets mean you are taking an extra gamble -- you are counting on all the factors that would normally go into making your product plus the success of the platform. Unless there is some superlative feature of the platform that makes practical something central to your concept that is impractical on more-currently-popular platforms, it seems like an unnecessary risk.
