I find the presence of MicroSloth very ominous. They can't want to break into the Linux market - software is not profitable on a platform where most software is free and open source, and M$ would get much more money just holding on to their stranglehold of the dull IBM-clone home computer monopoly.
The threat that Linux poses is not huge, but MicroSlop can't stand competition. I think MicroShaft are studying Linux very carefully for one reason - as Sun Tzu said, "Know your enemy, and the battle is half won."
They better guard that stall well, that's all I can say, and I hope they guard it better than Internet Exploder guards your credit card numbers.
