I imagine the end game is something like you pay Microsoft so much a month on a subscription, receive hardware that is preconfigured with and tied to your Microsoft account details or your company's Azure AD configuration and locked down with InTune, unhackable with properly implemented Class 3+ UEFI and Secure Boot, etc. You then purchase additional software subscriptions, such as your Photoshop, etc., through the Microsoft store, with Microsoft taking a cut like Apple.
If your computer breaks, pay the $50 or $100 insurance and receive a new one from Microsoft, if it's not folded into your monthly "Microsoft Technology Subscription."
So when Microsoft completes its takeover of the PC, what's the platform and OEM landscape going to look like? This endgame clearly puts companies like Dell, HP, Asus, etc. and the companies that provide parts like Intel, AMD in a subordinate position to Microsoft. They probably won't like that.
Will they give up? Will they try to start to make hardware for Apple? Will these companies embrace Linux and provide a third way?
