Glad to hear our South-Easterners are unhurt.
I think it'd take something a lot worse than this to actually do some damage to Britain. We've lived with terrorism almost constantly since the 60s, so we've got (possibly) the best anti-terror infrastructure in the world, as evidenced by the swift reaction of all concerned.
My feeling is that it could have been an awful lot worse, as the casualties, while numerous, are far lower than they might have been. There was also no damage to the infrastructure apart from at one of the tube stations, so there will be little to no disruption after the SOCOs and forensic people clear out of the tunnels.
If it weren't for the 37 deaths (at this point), I honestly think we could laugh it off. For a group trying to bring down the government/punish Britain for Iraq/whatever, they did a pretty poor job - it'll be like it never happened inside a week. Plus they attacked the most heavily-CCTV-covered transport system in the world. If they weren't suicide bombers, then the plod will find them PDQ...
Vyper: your last comment is one I heartily agree with. There's been far too much of that on TV and radio today.
One thing I found worth watching was George W.'s statement to the press at Gleneagles. Watching him trying (and failing spectacularly) to construct entire sentences on his own was hilarious.
Aldo: I hope that this will actually kill the ID card idea once and for all - such a system would have done nothing to prevent something like this...
