LINCOLN, Neb. (AP) – A new poll suggests most rural Nebraska residents own cell phones and often use the Internet to make purchases.  The 2011 Nebraska Rural Poll was conducted in March and April by the Center for Applied Rural Innovation at the University of Nebraska-Lincoln.  The results show that 91 percent of rural Nebraskans own a cell phone, and 72 percent of them often buy things online.  Survey manager Becky Vogt says the results show that technology has penetrated the state. But low-income people and the elderly still lag behind others in using technology and the Internet.  About 39 percent, or 2,490, of the 6,400 surveys sent out in the poll were returned. The surveys went to randomly selected households in 84 non-metropolitan counties.
