But do people really want pervasive computing ?
Do they really need technology everywhere ?
One company asked people about their opinions on "smart' appliances .
There were surprises . A "smart" refrigerator can buy
more food on the Internet , but people didn't want it , because it might make mistakes .
" Pervasive computing is as important as a telephone " , says Rebecca Blair , president of Inno Tech
Corporation . But some of these products are not useful , or even practical . Companies should learn more about the
technology that people really want .
