This shouldn't matter. If the task wasn't timed, then computer literate people would still be able to find the required features, while the illiterate people wouldn't feel comfortable clicking through menus and trying to figure out how to use the program in hand. If you want to be pedantic about this then using GMail or Outlook would probably have increased the scores some what, because a lot of people already know how to use them, but that probably doesn't answer the questions posed in the study since even most illiterate computer user can perform complicated tasks if they were shown how to do it (assuming they are of about average intelligence)
