David, don't worry about it, there are radicals in every crowd.  Some folks 
feel that being blind is like being part of some sort of race and view vision 
or people who use vision as inferior.  People of the same ilk who would with 
hold medical treatment from their children so they would be blind and thus of 
the "same race" that they are.  It's dangerous radicalism that colors advise.  
I think everyone's response though with out exception had good intentions and 
your interests at heart it's just some viewpoints are farther on the edge than 
others.

Personally you need to make the call for the best tool for the job.  I'd love 
to see you become a Mac user simply because for me it's been a great switch and 
the accessibility features are super.  That's for me though, I'm a totally 
blind user and my needs differ from yours.  If you can get away with screen mag 
or high contrast then I say go for it.  The least accessibility tools you'll 
need to use the better and more mainstream your experience and the least number 
of compatability / accessibility issues you'll run in to.  Keep it simple and 
if your vision changes deal with it then.  We'll be glad to help no matter what 
stage you're in.

Good luck and please do ask questions.  This is a wonderful list with a lot of 
really sharp folks on it and all sorts of viewpoints so you'll find the answer 
that fits your needs.

Take care
Scott
