Chitika Insights, a market survey and analysis firm, has analyzed IOS traffic from the last week of October -- just two weeks after the release of iOS 5 -- and found that nearly 38 percent of iPhone users had already adopted the new platform, with 30 percent of iPad owners doing the same. Owners of the iPod Touch were the least likely to immediately upgrade, with only 12.2 percent having done so at the time of the survey. The survey also determined what portion of iOS device users were on an earlier iteration.
