This plus Bring Your Own Device enterprise plans. Nobody wants two different phones to carry around.

Enterprise/business is merging with consumer phones.

Their mistake was not getting into the enterprise app market for iOS and Android. They still could since the software sort of sucks still (or maybe my firm is cheap).

Exactly this

The reason MS made sure you could Windows at home "for free" is that it would carry to the business world (where the money is).

I find it very hard to remember something that went from business to the home market successfully.

Nobody wants their clunky office app/device to be used at home, what they want is to use their consumer app/device on the office which is usually better and easier to use.

The Personal Computer.

Remember that mainframe you have at work that can crunch right thru spreadsheet numbers? Now you can have that same convenience at home. And this one can play Frogger too.

A Personal Computer (which started with the Apple I/II and after that to work, with IBM) is different from a Mainframe

Yeah, it's a personal mainframe. That's how they were marketed - it does the same things, but it's small enough to have in your home.

Not only this, but people became addicted to their phones. Use of one's phone now comes in first place, right ahead of sex, of things people couldn't live without, according to surveys. So people cared deeply about the phones they were using, unlike say when a company issues you a laptop.
