What’s the next platform?

I found this posting from All Facebook: The Unofficial Facebook Resource to be very interesting.
The Platform Wars Return To The Forefront, What Is Facebook’s Position?
With Google launching an operating platform with Chrome to challenge the other competitors (Windows, Mac, Unix, etc.) we’re seeing another clear sea change in our world. I found the list of things that the posting decided to say were critical to the new platform to be interesting. They’re cerrtainlly not the same as they were 5 or ten years ago…
•Reach
•Payment integration
•Viral distribution
•GUI components
•Alternative monetization opportunities
•Clearly defined and enforced terms or the removal of authority
Anyway, it’s worth looking at the shift in the balances of power for operating systems – PC/Mac, web-centric or mobile – a new war footing is here and much depends on it.
