My point about being 2k, is the same as that 98 thread in this forum. At some point (which I would bet will come before then finish 100% 2k support) Microsoft will change their driver model. Then companys wont make 2k/xp drivers anymore.
so while it is a good idea, and I fully support it. I think that any thing they do will be better served by wine on linux then as an entire OS. Most people want to run the apps, not the drivers. In 90% of the cases linux already has the hardware support they need, its the software support the windows users miss.
But if they could somehow get that 100% before the windows version after vista I could see it taking off and being a very popular desktop OS.
Looks like driver model changes are already happening
