Useful for what? Grandparents and stuffy offices stick to IE, but the majority technical users are running FF/Chrome/Safari/Opera. It would be a bad idea to write a B2B or photosharing app that requires WebGL. But, games, art, visualization and optional site-bling can benefit a great deal. Like most new tech, it's a good plan to target techies first and let the late adopters come in after the kinks have been worked out. Even though the spec has hit 1.0, the dust hasn't nearly settled on the implementations. Lots of demos only work on specific browsers or have been broken by browser updates. Meanwhile, MS is apparently extremely devoted to not breaking sites that used to work when they put out new updates. I'm personally OK with MS waiting until WebGL solidifies before putting out their first implementation (hopefully...).
