A recent blog post from Sarah Parez tries to answer some "want-to-know" questions on the upcoming Microsoft Office Web Applications.  With software as a service becoming more popular, Google has quickly become a competitor of Microsoft's Office Suite with its Google Docs.  Microsoft is aggressively fighting back by making its Office software available via the Web browser.

According to Perez's post, Microsoft's Office Web Applications will not only be available in Internet Explorer, but also Safari and Firefox.  Office Web will also be compatible on the Linux and Mac platforms.  Some of the specific answers Sarah Parez gives in her blog post:

Q: Do the Office Web Applications require Internet Explorer?

A: No! Office Web applications will work across multiple platforms and browsers including Safari and Firefox, too.

Q: Will the Office Web Applications work on the iPhone?

A: Yes, in the Safari web browser.

Q : Is Silverlight required in order to use the Office Web Applications?

"Mozilla's chief operating officer, John Lilly, is calling Steve Jobs' plans for building Safari's market share "out of date" and "duopolistic."

Lilly made his comments following the Apple CEO's keynote speech last week at the Worldwide Developers Conference, where the Mac maker unveiled a version of the Safari browser designed to run on Windows Vista or XP."

"The flaw can be exploited if the Mac user has enabled an option in Safari to "open safe files after downloading," Secunia said in an advisory Thursday. The security company has rated the problem 'highly critical'."

The usage share of Microsoft's Internet Explorer has dropped to 83 percent. Meanwhile, Apple's Safari has a global usage share of 1.49 percent and Opera has 1.00 percent."
