The gap between iPad and Kindle ownership is closing fast not just in ownership but in the way owners actually use their devices, ChangeWave found today. Of its current pool of respondents, 32 percent claimed in November to have an iPad as their e-reader. The portion was still lower than Amazon's 47 percent but is much closer than in August, when 62 percent claimed to use a Kindle and just 16 percent pointed to their iPads.
