I tend to agree with a report posted over in the UK by O2 which basically showed that the list of features listed as selling points on the Lumia phones were actually at the bottom of the list of activities the average user spends a number of minutes spent per day doing. Their study showed an average of 128 minutes per day was spent by their customers on smartphones and of that, the vast majority was spent surfing, texting, playing games, using apps, and social networking. WP specific features like using MS Office, taking camera pictures, utilizing the People Hub etc totaled around 5 minutes of that 128.
The point wasn't that they were accusing WP of doing the more popular activities worse than Android or iOS. It was that WP wasn't offering compelling enough reasons to show people that their way of doing those activities is any better than already existing and more established platforms, as well as ecosystems that people have already bought into. People often cite reasons like more security, MS Office integration, email, Nokia cameras, or things like People Hub etc as reasons to switch, but it appears not too many people really care about that stuff enough to rocket WP into a position of equal marketshare with iOS and Android.
What MS needs to do is stop highlighting the wrong reasons to switch, get a better grasp of what people mostly use their phones for and refocus their efforts on those items. The big stumbling block right now is that those popular activities are largely app-centric, and the app-gap presents an obstacle.
Just a small side note about email. Not too many people use email that much these days unless it's for work, and both Blackberry and WP really seem to have convinced themselves that email is better using a built in phone email client and "hubs". As someone who simply ported all of their personal email addresses over to gmail and uses the gmail app I can testify this is far less hassle.
