Well, while I personally still think desktop Linux isn't worth what you pay for it (even when it's free) - competition is competition. I refer to desktop Linux because the thread is about Win98, which not too many really view as a server OS. ;-)
If that competition results in better (longer, etc.) support for MS products, so much the better. This will be good for all of their customers.
Whether Linux finally matures down the road, or some other OS rises to replace it based upon the many things the Linux community has done (and is doing) right, I will welcome serious alternatives.
My own issues with Linux fall mostly into the categories:
* Weak hardware support (always improving, but a moving target).
* Instability (everyone complains about MS releases but try running a substantial desktop application designed for distribution X version Y on distribution A version B).
* Lack of application support (getting better month by month).
* GUI shell mania (Linux makes it harder to develop applications because you need to pick and choose graphic library targets for specific GUIs or families of same).
* Lack of anything remotely as slick as ActiveX (which I could be all wet about, be glad to hear more - and please, no jeers from the peanut gallery, the vulnerabilites associated with ActiveX are often just a side effect of its power - and I don't excuse any real flaws myself).
So I see this as a positive move overall. If pressure is what it takes to get MS to do this - so be it. If Linux is providing that pressure - hey, I thank the Linux community.
