First, the connection you're talking about is 50/25 Mbps, while Google is a symmetric 1 Gbps. Second, Google includes 1 TB of Google Drive, which Google normally sells at $50/mo.

Granted, it's cheaper for them to give you Google Drive if you're a fiber customer. And, of course, you might not even want it, but it's one hell of an extra if you want even part of it. I wonder if that's one of the things they're testing with Google Fiber: What do people do with a lot of cloud storage they have fast access to (at least at home)?

Even on the TV side, the comparison isn't that bad once you realize Google is throwing in a DVR (with 8-way recording??). They lose some ground because of the bundle savings (unless you count the Nexus 7 / local storage towards that), but the competing high-end plans are so expensive (~$200/mo for FiOS) and still a lot slower (3x download, 15x upload) that it's no contest, assuming you want the speed.
