I don't think a bundle deal could really hurt Apple if, in fact, they want to increase their .Mac membership. I subscribed for the first year, but didn't really see any compelling reason to continue it, so my account lapses today. With the imminent release of Panther and the automatic iDisk synchronization, I may regret that decision, but perhaps if a bundle were offered, I would consider renewing. What a run-on.
Further, I wouldn't mind seeing a renewal price slightly lower than the full first-time subscription price. I don't mind paying, but I wouldn't mind some more incentives ;-)
