But why would you want to have that? Simply put, with wireless you are trading the convenience of having no cables for essentially everything: Wired has better throughput, lower latency, lower bit-error rates resulting in less retransmissions (better goodput).

I'll admit there is one aspect where wireless might be interesting: Comparatively lower cost of initial set-up, especially when infrastructure is lacking. In other words, if you're trying to provide Internet access to a developing country (little existing cable/telephone infrastructure), wireless might be an interesting intermediate option. But if you're looking at a industrial nation where (rough guess) more than 90% of households already have some kind of cable/telephone/fibre infrastructure, wireless would be a downgrade.
