The problem is that the company’s monopoly won’t entirely be broken, due to the fact that many popular software program (including, yes, MS Office) won’t work on Linux, or even Mac OS X. Unfortunately, due to Windows’ large market-share, software developers will continue to cater to Windows. It’s a “chicken or the egg” type of problem, and unless it gets broken, Windows will still have a virtual monopoly.
On the bright side, at least FireFox has been chipping away at IE’s market-share (currently at 20-25% worldwide, and at almost half in parts of Europe). I still can’t believe that there are website developers would only design their sites for IE!

Psst - Microsoft offers Office for Mac OS X.

If Apple had a brain, they'd get behind the WINE effort. Since their core operating system is Unix, it oughta be possible to get WINE to work under it.
