Not true. I recall IBM promising to track your thinkpad if it was stolen with some chip inside. Assuming they go online with it.
I don't know if it was a service you had to pay for or not but it was offered.
You're saying IBM would have to track your device after it was stolen. IBM did not say it would prevent the theft of your device, even according to your memory. If you can prove that Apple ever made such a promise, you should take it up with a class-action lawyer if you think it's not delivering. They work on percentage, so you wouldn't even have to pay upfront.
And if you think IBM still offers such a service, if it ever existed, maybe you should shop for an IBM tablet the next time you're shopping for one.
