I have a T60p ThinkPad as well, and like you I have been using Windows 7 since the public beta released. I love the improvements and already prefer it to Vista. My Send Feedback works and I think it's an awesome idea, that can be improved but it's a great first step. I wouldn't expect a personal phone call from Bill Gates 8mins after I submit feedback, but I'm certain that they will aggregate and use the feedback to improve.
depends on the DRM..
