Time for me to clear some points:

just to clear things up it is illegal for an isp to give out information unless they want to or the police or whoever has a court order.
it is also illegal to trace the location of someone via their IP unless you have a court order.
I might add if they are suspected terrorist then they can get all that info without a court order. Thanks to the patriot act.
Unless the laws are different in US than in Canada, you are totaly wrong and only say what SHOULD be done instead of the real thing.
Police dont need court order to have IP logs, they just ask for it to the ISP and get it. Same thing for celulars, without any court order the police may ask the cel phone provider to locate you. This was valid way before the patriot act and is good in Canada/US. They cant listen to what you are saying, because thats privacy, but they can pin point your location. They have to do this, this is part of their licence to use the wireless network. Also, this information is not viewed as private data but as the property of the provider so they can give this information without you knowing it.
And yes, if you are probbed 100.000 times in a month, you can fill a police complain and they will see if this is random probing or if this is done by the same individual. I know because thats how my name poped into their list. Their system was probed over a thousand time in a week and they showed me the IP and user information of EVERY connection attempt.
Now about locating computer. With IP adress you locate people, not computer, again, you are totaly wrong! There are two ways to connect to the internet: network card and modems. Modems have a serial number that they send when they initiate communication to the server/router. This number is logged by the server. There are no 'official' repository of all these number associated with a customer but if for exemple you said that you internet connection was stolen and the robber used it to download child porn for exemple, the police could use this serial number to see if the connection was made from your computer or not.
The same thing is done with network card when you connect to a network. Exemple that since we are using a cable modem for exemple, the MAC adress stop there, the ISP only get the serial number of the modem, if I remember right.
So please in the futur, talk about facts, not about what you think that should be. Surfing the net is not anonymous anymore and never was. Its just that it require some energy to locate the user.
Want other exemple of non-privacy? Every word document you make has a serial number in it that link it to your machine. How do you think the FBI locate idiots who make macro virus? There are also rumors that AOL does something like this too. Also, now every US corporation has to archive all the emails sent/received by its employe. I dont know if it depends of the size of the corp or if it include them all tho. All thanks to the Patriot act...
All this being said. I dont think that Apple actively look for stolen computer. They have a list of serial numbers of stolen computers that they make availlable to any potential used computer buyer and thats about it. I dont even know if they can use it with software update, maybe they should...
