Argyll, what qualifies you to say what everyone else needs? In OS X you can magnify the whole screen easily enough, but you cannot magnify only a specific area of the screen. Computer Glasses gives you some control over what you magnify. I don't need it either, but I wouldn't presume to say that other people don't. In two years it has been downloaded from Version Tracker over 2,000 times so it's reasonable to assume that some people do find it useful. Indeed, if you had read some of the other reviews you'd know that they do.
