RE: Examples of when people need text alternatives for images

Good points, Shadi!

Moreover, it is important to consider first the examples are not directly
related to persons with disabilities, such as those mentioned by Shadi.

Best regards,

Regarding the "usage fees", it may be good to use the buzz word "data 
roaming" as an example of expensive connections (that are not slow).

Text alternatives also help searching for images (somewhat related to 
SEO but it is not really about improving the search engine ranking).

Also for your consideration, may be good to say "listening to the page 
being read out by a voice browser *or other voice output*". I am not 
sure if "read aloud" widgets on website are considered to be browsers.
