Suddenly, the entire tech world wants a piece of Google (Nasdaq: GOOG).

First, TheNextWeb revealed that Apple (Nasdaq: AAPL) had filed a patent for interactive spectacles similar to what Google co-founder Sergey Brin introduced at last month’s I/O developer conference.

Then, Yahoo! (Nasdaq: YHOO) hired long-time executive Marissa Mayer as its new chief executive, leaving the search king with a high profile and understandably large gap to fill.

And finally, Microsoft (Nasdaq: MSFT), earlier this week, announced new subscription plans for its online Office 365 productivity suite. The goal? Make Office a "service," CEO Steve Ballmer said in announcing the changes. Sound like anything else you know? How about Google Apps?

To be fair, Office 365 has offered online versions of Word, Excel, and more for months now. The difference here is that, in making the suite a service, Microsoft is allowing users to login to Office 365 from any Windows 7 or 8 PC, and sync their settings, work, and so on to the current machine. Log out, and the remnants disappear back into the ether, saved to a distant server for later retrieval.

Is this doomsday for Mr. Softy’s traditional shrink-wrapped software business? That depends. Historically, Microsoft has produced and shipped multiple versions of its desktop Office Suite for both Mac and PC customers. Microsoft has yet to announce any changes to that approach, referring only to a forthcoming edition called Office Professional Plus 2013 in press materials, TechCrunch reports.

Cloudy with a chance of trillions
We won’t know the full extent of Microsoft’s cloud commitment until Ballmer is ready to announce details. In the meantime, what matters is that there is a commitment. Mr. Softy is one of many embracing the shift to the online world, creating a trillion dollar opportunity for investors who buy in early. Want details?
