What medical apps are you trying to use on WP? There were some medical apps on Andriod that I couldn't find, but once I started searching the WP store for applicable medical apps I found some really good ones. WP finally got a WebMD app. Ehow is a good app with good medical information, and Bing Health and Fitness is one of the best one stop shop apps I've come across. Mumble, Zello, Skype of course, Viber are just a few of the apps that provide Teamspeak functionality. Playing downloaded music isn't a problem on Xbox Music, but streaming is another issue. It has gotten better with the updates but I've also heard it's been buggy on both iOS and Andriod. I think the biggest hurdle for me is going from a lively, activity intensive start screen, to a stale iOS start menu that hasn't really changed since the first iPhone. I like being able to respond from the notifications screen, but I'm sure there will be some limitations. Cortana integration even in beta is better in many regards then Siri and you'd assume they will have an iPhone 6 and 6S. Nothing else I own is Apple so it wouldn't be benefitting me at all.
