We already know that will not be the case. Most apps will not function fully or "as advertised" on WP without the developer getting involved. Then there are the legal issues which also require developer involvement.
The bridges are for developers only. They aren't for end users.
Talking of legal issues, has anyone actually sat down and gone through Playstore / apple store.. How many different versions of apps are there? Just look at a few of the 'game' apps. I'll kick off with one of my favourite time killers. 2048. I always used the original, but there are a plethora of blatant imitations of it. I counted 12 the other week, when I found it on windows store, no not 12 in windows store (lol). How many different defence / strategy games are just blatant copies of others?? It's OK for Google and Co to say they have the most apps, but statistically, when removing the blatant imitations of an original, how many do they really have??
Surely, from a 'legal' standpoint, this must amount to theft of a devs intellectual rights?? Or, as usual, are google immune from this type of behaviour, just like their tax evasion practices. Strange really, I should like droid, being a fanatic linux user and a rom cooker, but I just fell out of love with it. Clunky, little integration with Fedora, Opensus, windows etc. Linux was OK for cooking but android always seemed to be a standalone platform. Even Chromebooks had limited integration with it.
As for windows 10 mobile, I don't think the long game involves us social users. The 950 / 950xl are obviously aimed at the enterprise market, and I guess that's where MS is heading, especially with the abundance of users of W10. The only budget device that was 'unveiled', albeit it very briefly, was probably an attempt to 'let Google and Apple know they were still around'. What could be interesting is if MS developed the linux system they have been working on.
Anyways, sorry for going off topic there...
