> Let's take an analogy: Your Windows PC runs an OS very similar to the ATM across the street [...] Do you really expect your app to run on all Windows machines flawlessly?
Yes, I do. (With limited exceptions.)
Software often has minimum specs to run. Apart from games the minimum spec will often be for machines that are obsolete.
So (apart from games) I would expect an app created for one machine running MS Windows to work on another machine capable of running the same version of MS Windows. And those versions of Windows will last for several years.
Compare that with Android as applied to cell phones. Not everyone upgrades their phone every 18 months[1].
