Re: my banks are dropping windows platforms soon.
Don't worry...Windows10 for phones is bringing universal apps and therefore developers developing the apps for other platform won't hesitate to develop for win 10 as it will be quite easy to port apps from other platforms. Windows 10 will be a massive hit, and is definitely the start of a new Windows experience... So I suggest you to stick to the platform, your patience will be rewarded..��
While I generally agree with the second part of your comment, I wouldn't be sure to assume that Windows 10 will somehow open the floodgates for universal apps on the phone OS variant. Firstly, if BoA really wants to, it can already create a universal banking app for Windows 8.1 and Windows Phone 8.1. But the fact that they are
also withdrawing their Windows 8.1 support which arguably has the biggest reach of their entire customer base suggests something else is at play here.
I suspect that most people on Windows (desktop or tablet) use BoA through their website and that gives them everything. There's no need for a specialized 'metro' banking app when IE will do. The clamour for apps everywhere, started by Apple and echoed by Google, just doesn't carry as well on Windows and actually, I'm starting to agree. Why do I need a metro Facebook app on Windows? I never use it over the website which is fully featured and just works. Equally odd are apps that have come from traditional X86 roots like Adobe Reader, WinZip - do we really need an additional metro app for these? Apart from the confusion of what to use when, the development costs start to become unjustifiable, no matter how big a company you are.
Now I fully accept that on phone, a native app is essential, given its relative screen size/orientation and primary touch input mechanism, I get it. But there is also a growing trend that smartphones are getting bigger, browsers are getting faster and more standards compliant. Suddenly, navigating your banking website on say a Lumia 1520 doesn't feel like a bad proposition, who needs an app to feel special? It's not much comfort for those with smaller devices right now but the trend is heading that way.
