Question: What was the introduction date of this line of Macintosh portable computers, introduced in conjunction with the MagSafe?
Sentence (from "MagSafe"): The connector is held in place magnetically so that if it is tugged — for example, by someone tripping over the cord — it will pull out of the socket without damaging the connector or the computer power socket, and without pulling the computer off the surface on which it is located.
Relevant evidence: No
