Please fix Scroll Zoom in Lion
Despite not having issues with my eyesight (I do wear glasses, but that doesn't count) I use Scroll Zoom fairly extensively in my web-dev workflow. I always zoom in to see the graphic details or to check if there are some misplaced pixels or anything. I have smoothing turned off, because I need to see the exact pixels, not their blurred approximation.
But in Lion almost every time you need to Ctrl-Zoom In on something it doesn't work. So it goes again, open Preferences, Universal Access, Zoom, and reset [x] Use scroll wheel with modifier keys to zoom check box. Do it a few times during the day and you will get the feeling.
Ok, it is tiresome and annoying, but I can do it. Now imagine somebody who relies on this functionality to be able to actually use the computer.
