Value of the computer

In Beyond Access:Psychosocial Barriers to Computer Literacy, Stanley concludes,"... computer technology simply has not yet provided some low-income people with a compelling reason to make ownership a priority." (p.410). From this article we see that other devices (ie VCRs, CD players, cell phones, big-screen tvs, etc.) were purchased in low-income homes. Some of these devices require a certain about to knowledge to operate. Frankly, I accidently changed my ringer tones on my cell phone and can't figure out how to change it back... So if a person can program a phone, operate a DVD player, etc., I think s/he also has the capacity to learn the basics of a computer. Isn't computer technology in these items as well? I guess my question is if some low-income people already use computer technology, why is the computer itself not valued?
