1. Buy T-Mobile
2. Buy DISH
3. Buy Plex
4. Buy Netflix
Here's why:
Dish owns the largest amount of unused spectrum in the country. They also have a complete satillite network that can do multi-cast IP broadcasts over the entire United States (and Canada)
T-Mobile has John Legere and a built out Mobile network that covers most of the population of the United States.
Add these 2 together and you have the makings of a major internet provider. All known video content based on AI and your watch lists etc. can be pushed over satillite or the mobile network off peak so all of those YouTube videos, Netflix binging etc. don't congest the network. Because they don't have to do to the home wiring their cost per user would be half of everyone else and can massively disrupt the ISP business overnight.
Combine that with a headless home server that is hooked into the cloud, runs a simplified version of Plex, and has snap ins for the DISH tuners or satillite dish, T-Mobile service, cable modems if you don't want to use MS, DSL etc. and then Wifi, router and additional hard drives that just stack on top of the central unit and are automatically provisioned and can be customized in Windows, Android, iOS or Xbox and you have a killer platform. Add Z-wave and Zigby to it as well with a better version of SmartThings that's integrated into all of those devices natively and you start to own the home automation business.
Then create an xbox streamer with full 4K, Bitstream audio (not just Atomos decoding!) with plex integrated. It might as well be the default interface. Add apps in windows, android and iOS that allow seamless access of all content by the content not the channel like plex does and make it just work. Press a button on the top of the home server and another on the streamer and volia! Connected. Same for xbox Next game platform and windows 10 pcs.
0 configuration for everything. No harder than pushing a button to connect light switches, Philips hue, everything and all backed up in the cloud automatically as part of your monthly contract for your internet and cell service.
Then buy Netflix and capture all of that content in your platform of obvious reasons.
Once you've done that, adding a phone/andromeda device that allows you to consume all of this content is a no-brainer. Especially if they turn on the Android emulation functionality.
But finally, they need to take UWP and make it compile cross platform to iOS and Android yesterday and get Blazor going so that the same code compiles everywhere and just works without you ever having to own a Mac to do so, and give those platforms access to all of the content and preferential treatment to the Microsoft ISP. Android emulation only works if in the long term apps are being built in UWP and the only way that works is with iOS and Android (not Xamarin crap).
The world is going to content, Microsoft can be at the forefront and the devices come as a result. If MS executed this, and put John Legere as the head of consumer everything at MS and Nadella focused where he doesn't suck in the server space, they would be completely unstoppable.
