It's not like it was an accidental choice, you knew that you'll have to buy whatever Apple serves you in whatever form they want as long as you want to service that platform.
A Mac let's you write for iOS and Android. Windows doesn't.
You can do everything you could do on a Mac except upload the final build to the iOS app store.
To my knowledge there is no way to use native Apple tools to build iOS apps on Windows; but I haven't kept up with the tech.
shoe's on the other foot now.
if MS had done a better job in mobile, there'd be more reason to target windows for regular joe consumers, but they lost that market (for now anyway?). :(
Parallels/BootCamp?
perhaps I should have put that other part in quotes. that was the refrain from mac-bashers at the time (well, one of them). Everything revolved around windows ecosystem, it had the developer mindshare and market strength, etc.
It's not the same story today.
