There are currently 700 000 PSNow subsribers which I would say is a lot more than "a few". And my comment wasnt about how many people could use it, I said it can technically stream every PS3 and PS4 game since it can and OP mentioned it currently has 750 games but that has nothing to do with technical limitations. This is why I commented in the first place, to address that.
PSNow is remotely accessing PS3's and PS4's and remote play uses the same technology. You can read about it here:
"On July 2, 2012, Sony announced that a formal agreement had been reached to acquire the company for $380 million USD with plans of establishing their own new cloud-based gaming service, as well as integrating streaming technology built by Gaikai into
PlayStation products, resulting in
PlayStation Now and
Remote Play"
You don't need to sell me on Azure, I know it's great and never suggested otherwise. I will be using it shortly at work and have been researching it for months. I can still make an awful application that is hosted on Azure and so can Microsoft/Xbox. Like I said, just because XCloud will use Azure doesn't mean it will automatically be better.
And if you think I am saying PSNow will be better I am not, I am just saying you can't assume something will be better just because it is hosted on Azure or any other cloud infrastructure.
