I really like Communication Arts, Dwell, and Azure. I have a subscription to Technology Review, too, but they've moved to a more web-centric publishing model that makes the print magazine a little less edifying. I get Stanford magazine as well, but I don't think you'd be interested in that.
Oh, yeah, and JAMA. I am underwhelmed by JAMA. I think NEJM is better, but I pretty much never had time 3rd year to do more than page through the table of contents and see if there was anything relevant to my current rotation.
