This is really aggressive. It's so aggressive that it feels strategic. Google is trying to shift the market here. I think they have come to the realization that at a large scale people are not buying their philosophy that you can put everything in the cloud. By and large, we're putting selected things in the cloud for the purposes of sharing, but we're not making the cloud our primary location for our storage. That's what Google wants. They don't just want the docs that you like or need to share in the cloud - they want your whole hard drive up there. So they have calculated how much a "normal" person might be willing to spend on that and worked backwards from there. I strongly suspect this is going to accompany a wave of marketing and a big push for ChromeOS.
