I think it's a game changer
It's an early but important step. I think it's likely to be the first real step onto a slope that leads to not only enterprise VDI, but also consumer VDI, where people who want more than a browser-enabled media device (like a tablet) *still* just a browser-enabled media device to access remote compute resources that run in remote data centers. More than any other tech we've seen yet, It allows gaming and other locally resource intensive programs to become remote apps.
That has the potential to further current trends we already have in consumers shifting to lower-power, more portable devices, which has implications for the costs of heavier-duty kit. If almost no one is buying full-on desktop PCs, they'll become expensive niche products, assuming anyone sells them at all. (I do assume there will be some legitimate need for them, and someone will meet it.)
