ChangeWave, the technology trend-analysis firm, has posted the results of its latest e-reader survey -- compiling the results of interviews with 2,800 consumers early last month -- and finds that the market for e-readers comes down to two companies: Apple's iPad (market leader) and Amazon's Kindle (not far behind). Other e-readers received negligible interest in using or plans to buy over the next two months, with 75 percent of potential buyers indicating they'd get an iPad (42 percent) or a Kindle (33 percent) in the near future.
