Microsoft had to go back to x86 apps for two reasons. 1. WinRT devices couldn't run x86 (win32) apps. Thus customers who were frustrated and returned the products in droves. 2. Product name - if Microsoft had not named WinRT OS Windows, customer expectations would have been clear. 3. Lack of Emulator - Apple shipped an emulator whenever they changed processor platform but Microsoft did no such thing with WinRT, believing that security was more important than usability for their customer base - they were wrong and have still not learned the lesson. Apparently, the company's now working on an win32 Emulator for ARM * One reason Microsoft didn't do well in countries with poor internet penetration is because all apps MUST to be downloaded from the store on the device in question. Heck, even IOS allows an alternate download means through iTunes. Even after putting an option to sideload apps on both Windows 10 desktop and mobile, it's impossible for normal users to download and store the apps offline for later use. Stability on windows 10 mobile is far worse than on WP8.1. E.g - I've reset my own windows 10 phone more times in three months than I ever did in WP8.1
