IN hill-wrapped Naravaripalli, nestling in a lush valley where sugarcane and groundnut grows abundantly, forty-something Rajarathnam Naidu has never seen a computer in his life. So what if he's the brother-in-law of N. Chandrababu Naidu? Life in this quiet outback of 250 villagers in Chittoor district is laidback by the standards of its most famous son. Residents work in the fields in the daytime and watch TV on portable black and white sets after dusk. "I don't even know what a computer is," says the dhoti-clad Naidu, who is married to K. Rajeshwari, the hi-tech chief minister's sister.
