WebAIM's 4th screen reader survey results are now out, with almost 2000 respondents.

The main points this year:
-more mobile screen reader usage
-free and low-cost screen readers have increased significantly
-Apple use has increased (mobile-wise, Nokias are still most popular in Asia)
-web pages still suck

I found it unfortunate that the majority of respondents were North American, so next time they have a survey I'm going to alert the Orca mailing list, which is Orca/Linux users who are mostly in general Europe, India, and Brazil. That would help give more rounded results.
