Well it depends on what you're looking for and open to. For example I used MyFitness Pal when I was on Android and used it on WP, albeit the app experience was different. Then I looked into Health and Fitness from Bing and I haven't looked back. I used to use Google as my search engine. Never used Bing and thought it a waste. Now its all I use. Pandora works well on WP but there are other apps unique to this OS that you might like better if you're willing to experiment. One thing I will say is when it comes to photo apps, Nokia pretty much sets the bar. My biggest piece of advice is have an open mind.
