I've always kind of kept one eye glancing at WP over the years waiting for the app situation to be resolved. MS has pretty much resolved all my grievances about missing OS features but the app gap still remains and efforts to lure developers even including outright paying them to develop have all met with little to no success.
The newest draw to getting people on WP devices is now Continuum. For businesses this is a decent feature. But is it a "I must have this" for the other billions of people who just use smartphones for personal use? No. Let's be real here. How many of your friends, family, and co-workers would even have something like this on their radar as something to care about? I think there's a lot of excessive fanfare being given to Continuum by MS for a feature that's not even going to register with the vast majority of smartphone users. The problem for MS is that they're banking heavily on Continuum and are in a situation where they have to keep going after mobile now because without W10 mobile, what's even the point of having Continuum?
Next up is their effort to lure devs with porting tools combined with universal apps to close the app gap. I've said it before and I'll say it again because it's already happened. MS could literally walk into your home and develop the app you don't want to FOR you and developers still won't care. They just won't, no matter how easy MS tries to make porting. The simple fact of the matter is that developers aren't willing to go to the effort of developing and maintaining an app unless it's for phones where the users are. That's always been MS's mobile conundrum. No apps no adoption - no adoption no developers, no apps. Even were MS to pull a Blackberry and allow Android apps to run on WP, that won't work any better than it did for BB because Google simply doesn't grant access to Play Services unless you run their android. Without Play Services you end up loading crappy unsupported freeware versions of the Play Store apps and look how well that's worked out in the past.
The big unanswered question is if there's even room for a 3rd major OS on mobile. I'm going to say no at this point. MacOS and Windows have dominated home and business desktops and laptops for 20+ years now, and I don't see the duopoly situation changing any time soon for mobile, where the current duopoly has already fleshed out for nearly a decade already. In that time how many have tried to break it? The short list answer is: MS, Blackberry, Amazon, Facebook, Ubuntu, Mozilla, Samsung, WebOS, Jolla. All former or current heavy hitters in the tech industry aside from Jolla. Out of that list only MS and BB were able to even show as a miniscule blip on worldwide marketshare compared to Android and iOS.
It's not that I blame these companies for trying or that I want to see them go away. Absolutely and unequivocally no. But when the question is will I buy from any of them in today's climate then my answer must likewise be no. If I'm unable to not only get the apps both major and niche I want, but also multiple choices of those, then no. And I won't settle for having to use my browser or apps that are basically the browser in a web app wrapping either.
