So here are some free options to make ICT in your school more accessible...
Microsoft Reader (all free, a three-step install - Reader, the TTS engine, and the "Read in Microsoft Reader Add-in" which allows instant conversion from MS Word. http://www.microsoft.com
for free books - http://etext.virginia.edu
Firefox/FireVox http://www.mozilla.com/en-US/firefox/ and http://www.firevox.clcworld.net/ or Firefox (1.0.7) with FoxyVoice http://www.filehippo.com/download_firefox/?390 (make sure tool preferences are set to NOT automatically update software) and the FoxyVoice Extension at: https://addons.mozilla.org/extensions/moreinfo.php?id=269
Opera (with speech enabled) http://www.opera.com/
GraphCalc - a marvelous free graphing calculator that allows easy intro of math notation into word via copy/paste (and may eliminate spending $100 a student on TI calculators)
Click-N-Type - perhaps the best, most flexible on-screen keyboard that talks to you as well in a ton of languages
Dasher - another "higher needs based" on-screen keyboard
Google Accessible Search (blind-low vision support)
SENSwitcher (early childhood, CI, etc)
Adobe Acrobat 7 (reads pdfs)
Another critical free resource is teaching students to use free on-line storage to back up their files. British Telecom (new), Google's G-mail and Yahoo Mail all come with 2 gigabytes or more of storage. The simplest way to use this is to attach files to message "drafts" and save them. This creates data storage that you can access from any computer (scan your passport, etc and upload it this way before you travel for one great potential problem solver).
And remember, Google now offers free calendars, word processing and spreadsheet software that not only is remotely stored but can be shared by workgroups, especially student workgroups.
