In many places in the UK It's possible to get a totally uncapped, unbandwidth-shaped broadband connection for under £15 which is actually usable (20Mbits down, 1.5 up).
As such, I don't agree that the bandwidth is necesarily an extra charge. The majority of homes in the UK already have bandwidth because they have broadband anyway - and the clever ones have Be* or o2 Broadband without caps. For those people, the voda femtocell may actually be pretty useful.
I've got friends who have great broadband but no mobile signal where they live: they are farmers. They spend a lot of time outdoors. This is *perfect* for them.
