I really like these two takes on the Google-Motorola deal.
Ben Brooks points out that Motorola makes a heck of a lot of modems (they also make A LOT of cable boxes). You could argue that this might be about more than patents. Why own the pipes when you own all of the faucets.
Andrew Cunningham points out that this might increase FTC scrutiny. I hope they also consider what leverage they may exercise when they can control the routers of the consumers too.
