ALViC and Vinux are GNU/Linux distributions. A GNU/Linux distribution consists of the GNU/Linux operating system and a set of popular applications. In ALViC and Vinux, the screen reader Orca is built-in and enabled by default. Vinux and ALViC are comparable to - Windows + MS Office and other applications + JAWS/ NVDA. Detailed comparison among JAWS, HAL, NVDA, VoiceOver and Orca is available at the following link - <a href="http://easi.cc/archive/screenreader2011/Screen_Reader_Comparison_Study_2010-INIB-with%20page%20numbers.htm">Practical Screen Reader Comparison: A user-oriented approach</a> Screen reader user survey by WebAIM is available at the following link - <a href="http://webaim.org/projects/screenreadersurvey4/#lowcost">WebAIM: Screen Reader User Survey #4</a> Hope you find this information useful.

She also has nvda on her windows computer which she prefers to jaws which the schools promoted. I use ultimate edition on one of my computers but didn't find it had good vi accessibilty. I didn't know about vinux. We also have an apple mac pro and I have had a brief look at the voiceover on it which disabled the mouse and forces the use of the keypad. I find that voiceover on the iphone and ipad is great except for on the internet as it stops reading link words and its too hard to find them with a finger to continue reading. Can anyone give me a comparison of the functionality differences between alvic, voice over on ipads, voiceover on macbooks, nvda and jaws? I need something simple to learn and simple to use. I don't care about cost, just a true comparison of functionality please. Thankyou Alicia brown </blockquote></div>
