Something that has been annoying me for a while, is the fact that Nokia has pushed getting partnerships for “big name” apps, like Draw Something, Words with Friends, Viber, CNN, Groupon etc, for WP, and forgetting about their other users. Yes, Symbian & MeeGo are dead. However, Symbian still has a larger user base, as does Asha. Having these apps available to ALL the platforms under the Nokia device umbrella, would go a long way.
It would be simple, have a Qt (Symbian & MeeGo-Harmattan (even Maemo5) with possibility of Asha if Qt is supported) and Windows Phone version. This would actually go a very long way for Nokia, in ensuring their users aren’t angry that they are being left behind, for not swapping to WP. It may also stop, or at least slow, the attitude of people switching to Android because Nokia “does not care”.
Again, this is just my opinion, and I know it will never come to fruition.
