Interesting - but I'm not sure what this gives me over something in a similar price range, for example:

Presumably either you know something about routers and want to enable QoS, install your own firmware, or use some other advanced feature - and you spend money on a decent router. Or you don't, and use whatever your ISP provides (which if it's bad, you blame the ISP for without thinking twice).
So perhaps this is the new router bundled with Google Fibre?
