Much as I hate the idea of defending them the ability to get internet access through other BT customers routers at no extra cost does give them an edge. Albeit you have to blur the definitions of range and coverage a bit and the swap-over between access points is not quite as seamless as adverts suggest, but hey that's marketing for you. The other thing and I am surprised BT does not push this is "power" of security. Ever since the debacle where black-hats completely reversed the v2 HomeHubs and published the keygen online BT did raise its game significantly. It takes your typical script kiddie neighbour what.. 3 weeks to brute force a SKY or TalkTalk router compared to modern BT router taking significantly longer.
