Looks great. These kind of offerings are going to be free. There is no reason to charge for people to either evaluate your product or help service your portfolio.
Especially not with Open Source around. Great to see Microsoft is moving it business models around. Very important for them.
Nice participation from the side of Microsoft.
Also if materials are better organized i.e. compared to similar Open Source offerings, i.e. more professional, i.e. the quality - it will be competitive. I.e. more edge but state-of-the-art price 0 (compared to Open Source, i.e. "freemium")
Anyway, end of exclusive access. It's about the for all market as well.
Ubiquitous computing is just imaginary - without any margins. IT and software ... system interactions ... constructed into all kinds of stuff. I.e. all stuff becomes "part of nature" ...
