Most North American airports are the same.
I know we take the p1ss here on PPRuNe out of Heathrow and/or BAA for being more into shopping than aviation functions, but they do have such a good selection of facilities, provided of course that you are prepared to spend money there.
One thing still somewhat missing almost everywhere is DECENT restaurant facilities rather than yet another *&$%? Costa Coffee. Why have airports worldwide been unable to make a go of proper restaurants. There's one in Helsinki (by about Gate 28) which I always use when there, a pleasant place to while away an hour. Even Heathrow doesn't seem able to run to this in T1.
But compared to any US terminal I know, Heathrow is splendidly equipped.
