It really depends if Win8 RT or Windows Phone was going to appeal to your development team, your advertising team and ultimately, your future customers. Given how both have been selling, I'd say that's a stretch. So far only Nokia has shown interest in WP8 and Win8 RT. Prior "partners" have discontinued their endeavors in both for the most part. Jolla will have to differentiate themselves. I think they have enough points to do so easily.
