Ask the users.
Or is that too much like common sense?
I suspect that quite a few Iphone users are like me & my mum; we have Iphones because of the 'walled garden' environment.
Yes, it's a pain when I've written something I want to run on my phone, but why should the whims of Epic (who are disliked for many reasons) get to wreck a nice system? Disruption is not good for the market....
Also would this mean that my Smart TV can now run any app I want to run?
Can I run an app from Sony on an LG?
Or a Ford app on a Mercedes car?
Or go into Waitrose and buy Asda SmartPrice products?
