Doug. The osx operating system has a screen reader built-in. It's called voice over, and for the most part, it works fairly well. It has it's quirks, but what doesn't. Any OSX version 10.4 (that's tiger) or later will work with voice over, so you're able to basically sit down and use *any* mac that is running tiger. And, that's the main benefit here. You buy the computer, the os comes with it, and you need spend nothing extra to make it accessible to a blind user. That more than anything else is why I'm so drawn to the macs, though the longer I use them, the more I find to recomend them. I've had my current machine only about 6 months, but before that I had one since only a few months after osx tiger came out. It came out in April (end of april) and I bought my minimac in August. That was nearly two years ago. That mini went to my son, and I got another mini, and a macbook (the mac laptop) They're both nice machines.
