James Lileks delivers a telling plug for the new iMac: Finally, I have to smile at the people who scoff at the movable screen - how many times do you have to reposition the screen? they ask. Well, at least once a week I call my wife in to look at a picture or a snippet of video, and to get the best angle she has to sit in my chair while I lean over and type commands. The pivotable screen is tailor-made for showing other people what you’ve done while you sit at the keyboard - a small thing, sure. Sure. But it confirms my suspicion: that bastard Jobs is watching me.
