WTF? (Score 2, Insightful)

This article makes it unclear if WGF 1.0 is basically DirectX 10.0 or a Longhorn-specific system. If it isn't available to users of older versions of Windows, there is little incentive to rewrite code specifically for it. I think the adoption of Longhorn will be slow as I haven't heard any really compelling reasons to shell out the money for the upgrade.
