Microsoft Office for Linux

Within the next couple of years, a linux version of Microsoft Office will be released.
Stuart Cohen, chief executive for the Open Source Development Labs, said: "They did it once with Apple, they will do it again with Linux"

I'm a Linux & Windows fan at the same time (or rather a partial time fan lol), and in my opinion it's a great new for both parts.
For Windows, the Office software will be in one more market, and on the Linux side, Open Office will have to improve if they want their software to be still used.
