Well we've had it for 2 years, we switched from Telewest to BT as soon as we found out we could get it, after checking at least every month for years. All this while a street about a hundred yards down the road had had it for several years already. Then of course was the way we only got full speed rather than ~1.1mbit about 6 months ago.
So yeah, I exaggerate, but still not fast by any means.
