I was particularly surprised that Microsoft accepted Bitcoin this early compared to Google or Apple.

I'm sure Google is contemplating ways to implement or incorporate, but MS jumping into the fray this fast is good on them.

Apple on the other hand has made their own bed with Apple Pay, which they'll probably promote market aggressively to it's sheeple followers until Bitcoin does make a mainstream splash.  Only then, once it's available and easily implemented into Microsoft, Google, Facebook, Amazon's etc interface will Apple eventually jump on the bandwagon.

MS incorporating it is a good start.

One million dollar coin will never happen, but ideally is should reach 3~10 k within few years. I don't have any data that back up my claim but all I could say is that we are on the right path. So if bitcoin ever reaches 1k I will only sell maybe half of my coins.
