I've been told by a real world user that Windows 7 resolution adjustment works pretty well. Apple's 27" iMac may look, to middle-aged eyes , quite a bit better running Windows 7 than running OS X 10.6.
Resolution independence. Vastly better remote control functionality. In what other domains does Windows 7 pound OS X?
 Note Google now scales their search screen for presbyopic eyes. On another front, in winter aging fingers don't work all that well on the iPhone touch screen either. Too dry. Jobs wears reading glasses and I bet his fingers aren't much better than mine. Denial?
