Of course, M$ is calling their OS “the first cloud OS” so there could be fireworks…
Of course, I think Google’s patent is nonsense. It includes just about everything one can do with a networked OS since the 1980s, so it’s more than a little broad. I think it’s aimed at the VDI stuff in general and Chrome OS in particular but who knows what M$ thinks their OS does? Wouldn’t it be cool though if Google could receive an injunction to block M$’s whole empire? Is Mutual Assured Destruction now keyed up?

“Cloud OS”? Sounds more like a slightly refined PXE.
