I have a lumia 920 and Im afraid that the selection is very very sparse at the moment, I suspect that until market share increases, it will remain like this for a while. I love WP8, it is a really well thought out concept, luckily I have an android tablet so I have all the apps I want on that, so don't feel any regret over switching.
If apps are important to you, then stay on droid, but if you can get by with other means, then WP8 is excellent, or you could wait for the apps to arrive as well as the rumoured Nokia EOS model in July
