If Microsoft were to announce that the next update to Windows 10 would remove 32-bit compatibility, there would be an uproar. Not only are many popular Windows programs still 32-bit, it's not unusual for enterprises (or individuals, for that matter - Starcraft on PC never had the long hiatus it had on Macs) to still be running DOS-based program from the 90's. Yet Apple dropping support for 32-bit is practically a non-issue. Everyone just kinda takes it in stride. What's behind the difference in mentalities?
