Thanks, I tried persevering with gnome for quite a while because I wanted to use Linux day-to-day. But all of the accessibility stuff at the time was a subset of all of the things that ordinary user could do, that just wasn't enough when I started working and I needed something as full featured as Apple's offering.

I mean I'm obviously going to try and change the state of accessibility and Linux by submitting bug reports and getting involved, but it's a long slow process and in the meantime I need a computer that works.
